502 "PUMP GAS" 9 sec build results-2008 updates

Final build for 2007,

The car:
87 mustang hatch, 3150 with driver(180)
8.8 rear with welded tubes,girdle, 3.27 gears
Suspension is southside lowers, upr adjustable uppers, stock coils, strange 10 way shocks
Front has upr k-member/coilovers 90/10s, dropped 1.5" for hood clearance, header clearance (4" cowl hood)
Transmission is c4 with brake, 4800 stall
Tires are 28 x 10.5 et drags on 15 x 10 weld

The engine:

502 CI
DIVE block 4.39 bore , 4.14 stroke , 6.7 h-beam rods
Pistons are je's srp forged dish tops
Camshaft is a lunati solid roller 255-263 @050 with 675 lift on a 110 LSA/106 ICL
Heads are out of the box blue thunder ford cj port 2.25/1.88 - 80cc
Intake is a victor with a 1050 dominator
Headers 2" super comps
Compression ratio approx 9.5 to 1 , according to srp site
Timing set at 35, which I will play with this weekend.

The shakedown:

altitude - 800 ft , temp around 25 c

First pass shut down past the 1/8 as i was not sure on steering, car stability, etc. PROBABLY more scared than anything not to blow it up as my windsor did last pass out in august of 06

It went 1.43 60 ft, 6.35 in the 1/8th so i knew it was capable of 9/s

Next pass out I thought if she holds past the 1/8 we are going for it, and it was a handful till 300 ft as they werent spraying, rain clouds rolling in.
Went thru the traps at 10.04, 133.4 mph, rpms were at 6600, 1.41 60ft
I was surprised at the rpms, and seeing the mph, the motor looks to be all done at less than 6300. Loose convertor and all, Im putting in 3.27 gears this week to see if it will mph out the top, as I was all done by 1100 feet with 3.73/s

Well that was it, at the track 2 hours and its rained out till next week.

Over all very happy with the motor, tons of torque, have to get used to the lower rpms, but if it will run 9/s this weekend going thru the traps at 6000 rpm, on 92 octane, it will make my year !!!!

Will post results this coming weekend, as i will try the gears, look at jetting, timing, valve lash.
Cant wait.......

Later Mark.

That thing is hauling the mail for 3300+lbs. I know guys with more cubes and more compression and their not going that fast. Congradulations!!!

Good show and I like your cam....keep us posted........D

that's awesome. keep us posted on what the gear change does for it.

Good show and I like your cam....keep us posted........D
This was my last part to buy, and the hardest decision, as of my compression ratio being so low, but i thought worst case get the heads milled or put in different pistons this winter if the cam was not suitable.
Lunati voodoo #64034, very happy with this cam.
Thanks, guys will post this weekend as the gears went in last nite. Reason for 3.27/s is I will spray it in the next month or 2 with a 150 shot and will need the gears for mph.

Nice shakedown runs, very impressive for a pump gas engine :shock:

Keep us posted!

Good news and bad news.............
went out yesterday with the 3.27 gears, first pass i forgot to change my shift lite, so i was shifting at 6500, car went thru the traps at 6100, 9.94 at 135.8 mph !!! Finally hit the magic 9/s!!!

Second pass i shifted at 6000, car went 1.40 60ft, 6.33 1/8 at 109.1 mph, and 9.87 at 136.9 mph !!!

I was very happy, and this is more than i could of imagined for this combo.

3rd pass they forgot the change the tower back to 1/4mile, as a few top fuelers ran before me.

4rth pass, well.......i turned my transbrake up to 4800 to see if i could get in the 1.3's 60 ft, and BOOM!!!!
My ALUMINUM drive shaft is now missing an ear and a ujoint.

Im going to post about what driveshafts you guys are running in the other section as im curious.
Ive definately found the limit for aluminum.

Next weekend im going to concentrate on tuning the car and will post more results from jetting, timing etc.

Well guys, having so much fun with this car, racing every weekend, ive forgot to tune the car. I have 60 passes on it now, never laid a wrench on the motor since it fired........
Today was license day so i goofed around with the transbrake.
Best 60 foot to date on a well prepped track was 1.36 at 3300 launch
Today, mediocre track, cooler outside ( 21C) i kept turning the brake up till 3800 was a 1.38 60 ft.
Very good day of testing, as the car went 9.76, 9.756 on my last 2 license runs.
2 passes after that were 9.702, and 9.721 at 139.10 mph

I cant say enough about these motors, as they are torque monsters, and make way more power than I thought, as i was hoping to just hit the 9 second mark, and have done that with ease.
Closest i can figure is about 660 hp, and im sure torque is up there with it...
Im sure there is more in it with timing and jetting, but what the heck for??

Best part is, there is no tinkering like a small block................ :D

I had the car weighed at the track which the guy told me was 3155lbs with me in it. Now i have to go back to our local coop to see if this is accurate,as thats where i weighed it earlier........ :evil:

The car leaves real straight. Do you run a airbag? Looks great!!!

No , no airbags. Rear suspension is lakewood lower arms, stock uppers including bushings...........ya i know, i ordered new upr adjustables for this week............stock springs with 50/50 drag shocks. The main reason the car launches so straight is the antiroll bar. Before the antiroll bar the car launched like a twisted pretzel :lol:


As well, the end of this month Im taking the car to the chassis dyno for kicks, and will post results.

Any guesses??

Just curious. Who's antiroll bar did you go with and how did you set it up? Any preload added to pass. side or did you leave it neutral. Thanks again!!

I actually made my own, but if i was to do it again i would probably buy a upr setup. They have some good rear suspension packages as well.......I did preload the passenger side a bit, and i should probably preload it just a bit more to get equal tire lift on each side, but it works very well :D

Thanks!!!

Chassis dyno results:

Pulled from 3000 to 6300 rpm - 565hp , 505 ftlbs tq

The curve was as flat from 3000 to 6200 on both hp and tq, varying maybe 10-15 points from start to finish

Taking in consideration for the drivetrain, the engine would probably dyno by itself around 685 hp and 615 + in tq.

Your car definately impresses! Those are great numbers on pump gas and at that weight.

Thanks. The greatest part is at the race track, when everybodies running $3.00 /L of fuel, at 10 passes a weekend, probably $80-100 in fuel, and I dont spend that in 3 + weekends :lol: The other most incredible thing is the low rpm, and the amount of tuning and work that must be done at the track............NONE :!:

I am impressed with your combo.

I want to run on 93 octane, 10.0 to 1 cr and pull about 130 mph in a 3450 lb (raceweight w/driver) Turbo Coupe.

Your camshaft selection looks good. What rpms does the engine idle at?

With the low CR, I would say you don't have any draggging starter problems.

Alan

I have it idling at 1400 when warm, so it doesnt load up with fuel.
As far as starting when its warm, it does crank hard, but with a good carb setup, it fires right away.......

bump

what kind of axles and carier are you using in you rear end?

what kind of axles and carier are you using in you rear end?

31 spline moser axles and spool.........

Can you send me a list on here of what cam you are using and crank and rods lengths and piston. Are the heads ported or stock. Thanks.

very fast for such a mild combo, do you drive it on the street much? what have you done to the block as far as oil restriction, type of cam bearings, main caps? what spring seat pressure are you runnimg , timing, jets, PV,s , carb spacers, ? thanks

all the info is in the first few posts..........heads are "stock"

It could easily be driven on the street, but I do not
I cant justify how it would react on the street with this much power and my lead foot :P
As far as the block mods i will know shortly when it comes apart for a freshen up. I do run a torrington front cam bearing though..
Springs are set at 210 on the seat, timing 35 degrees, 90 jets/no valves/no spacers

Updates for 2008 season..........

1.32 60 ft
6.05 @ 113.5 mph 1/8th
9.51 @ 141.5 mph 1/4


Changes made in the offseason,

Skinny kid glass nose
16 V battery system
Jomar 1" carb spacer
Canton windage tray
New rollcage to certify to 8.50

Still fine tuning the rear stock suspension.........hope to be in the 9.40's next week 8)

Impressive times. You know how much it weighs with the new front end? Thanks....

Impressive times. You know how much it weighs with the new front end? Thanks....

When i ordered the front end it was supposed to be 11 pounds. When I got it it was 17 lbs................factory nose is 23 lbs :(

But i did manage to loose some other weight in the old cage, took out the crash bars in the doors etc.

I will confirm this weekend, but it should be 60-70 lbs lighter this year.

If anybodies interested, the crash bars in the doors are 17 lbs each door :shock:

what year door was yours? i took out my door beams and they only weighed 10lbs.

mine were 87 doors with about 5" wide crash bars, but you are right also, as ive seen 91 doors with a lot smaller bar.............maybe 2" high?

yeah mine where only about 2 to 3 inches wide. i weighed the roll up doors and got 78lbs. i weighed power doors and got 80,81lbs. removel of door beam and door panel gave me a reduction of 20lbs.

so what is the easiest way to remove those bars ---- does it have to go back in the paint shop when you guys do that !!!!

so what is the easiest way to remove those bars ---- does it have to go back in the paint shop when you guys do that !!!!

no paint shop involved.................put a cutting wheel on your hand grinder, and cut the bar as close to the ends of the door as possible.

just "DONT" cut to deep!!! The exterior of the door is behind the bar :shock: :P :P :P

cool ---but i was just thinking --cant roll the windows down anymore so how the hell do i get it out of the enclosed trailer. ????? i guess i need to by a winch.... thxs guys

I'm confused - The safety door guard beams aren't anywhere connected to manual window mechanisms.

i have power windows still operable in my car !!!! the only way i can get those crash bars out is to gut the whole door --correct ????

i have power windows still operable in my car !!!! the only way i can get those crash bars out is to gut the whole door --correct ????

it is "easier" to take the bar out with the window out, but I think it can be done with it still installed

I still have all my windows/mechanisms installed.

On another note, i took out the crash car because i now have most of a 25.5 cage with the X bar in the door area, so i didnt feel it was neccessary...........................safety first 8)

I'm confused - The safety door guard beams aren't anywhere connected to manual window mechanisms.


Me to, but for different reasons..........Nick, how do you load the car now without a winch?

And why cant you roll down the windows?

its a bitch------ i have the x bars in the door and a funny car cage so i do it dukes of hazzard style !!!!!

when i take the crash bars out i was also going to gut the metal and power windows speakers etc.....

oh by the way sorry to mess your thread up !!!

Bump for a member.........updates coming soon!! Should be in the 5's this year, no motor changes;)

Very impressive times for that motor.

Yep thats one quick 501 Bud !

Thanks guys, its the little things that really make the difference;)

First let me say very nice combo and i was just wondering what you paid for your heads and was there any special setup for them .
Also do you think if someone was to duplecate your combo would they be better off running a 521 or 545 or stick with a 501.
Also wonder the reason for running the 501 over the rest of the strokers.
Thank you very much for your info as i am hoping to start build a motor very soon.

Cant really tell you the price, as they were in with other stuff I purchased, but I can tell you they are out of the box heads as the casting is still in the runners........availability I couldnt tell you, but everyone seems to be going with the TFS streets as they are a very similar head in performance.

To duplicate this combo with a bigger stroke, it would lower peak rpm, improve torque...........if you need it........not certain as to hp increase, but it would make the same power at a lower rpm.

Really depends on what your goal/application is?

Well the motor will be going into a 93 mustang ,the weight will be around 2800 lbs.
I have a C4 with a 4500 stall and a brake/8.8 rear with 4.10s/33 spline axels/welded tubes and c clip eliminaters.
I have southside uppers and lowers also.
The block is a D1VE already 60 over so i will prob. take it 80 over .
I also have a ossy tunnelram with a single top but i dont know if i am going to use it as i think there are better choices out there.
So i am not sure what stroker to go with but it has to be pump gas because i will be driving to the track every now and then and the rest of the time it will be trailered there.
I just want to have a reliable fast combo on pump gas {for now anyways}
and i am having trouble deciding on stroke and heads but i would like to run 9s with this combo that is why i was looking at your combo .
sorry for the long post but there are not to many BBF guys around where i live.

Thanks

Updates?

I was eyeballing the same cam for my street car. Looks like it will be easy on parts. For your combo have you considered backing the cam timing down 2* to see if it will pull a little higher rpm?

What valve-springs are you using?

.

Updates so far........

* Went back to 12 volts from 16 volts........installed a Optima yellowtop
* Installed an altenator (+ 16 lbs)
* Installed mufflers
* Installed front aerospace brakes (-32lbs)


Went testing a bit 2 weekends ago at a T&T.......wasnt really counting this as it was so windy, it took 2 of us to open the trailer doors , but got it to go a 9.52 @ 141 mph, so I didnt lose any ET......should know for sure next weekend at my first big race;)


I havent considered backing the cam off..........I like the launch too much:p

The springs were also in my previous motor, not certain on the part#, but they are a K-motion 1.55 diameter, with around 500 lbs per inch.
They have taken a beating with 100's of 1/4 mile passes and see no reason why they wouldnt work on the street. The cam is a "street roller" anyways.....

Just got into the BBF scene this last fall with a 513 in a 93 notch. C-6, no stall or brake, Moser rear, anti roll/strange adjustables.front coil overs, rear Morosos, 28X9 ET drag.

So far I am running a 10.22 on 93 and looking to squeeze a bit more out before the end of the season.

Running 34 degrees timing, 92f/96r jetting on an 1100 Dominator Pro.

Going to try a colder set of plugs NGKR5671A-9 and try messing with the timing a degree or 2. Also some suspention adjustments.

Apart from that any suggestions?

Your stang sounds amazing, I am very impressed you are well into the 9's. Hope the rest of the years rocks for you.

Thanks,
Rob

tell us more about your engine please.thanks

These motors like timing put 38 degrees in it and I'll bet you will see a diffrence Joe.

Yeehaaaw!! 3 passes in a row yesterday...........1.27 60 ft, 5.92's to the 1/8th, and 9.35/9.36's in the 1/4 !!!!

Only change so far is my front end limiters.......and they work:D

Great runs man hope i can get mine in the 5s soon. Do you still have the same BT heads. how tight do you got the front or how much travel do you have? Did you get any video of the passes?

feetfirst,

Is that on motor if so that's very impressive for a 501" Pump gas motor?

Later Mark

Very impressive, thats really fast with "only" a 501 and "out of the box" heads! What did you finally settle on for your IC? I've got a similar setup and have been experimenting with changing ride height to alter IC location to help with wheelspin off the line. Hoping to get to the track for the first time next week, if the weather warms a bit.
Gary

Yes, this is with this same 9.5-1 out of the box bluethunder heads........91 octane gas. I havent changed anything all year, other than playing with front end limiters.
The car is currently set up with 45" IC @ 110% AS, shocks on 7 all season long, and really wheelstand happy......which was fun.
This past weekend I tightened the front end down, as I was in the points running, and it was a double points weekend.
Only had 2 " travel left, but man it worked great....9 passes total, 8 out of 9 were 1.27-1.28 60 fts...

I run Procomp class which is the same as Open Comp down your way, with a 1/10th breakout on your dial....+ a bit of room;)

Here is how it launched tied down...

feetfirst,

Very impressive that's a Bad *** car,is that on motor if not still impressive?

Later Mark.

Yes, on motor;)

Ive been trying to drive home the message that you DONT need a 14-1 motor to run in the 5's at 3000+ lbs, let alone heavily ported heads or all the fancy stuff..........sure its easier to do, but definately not neccessary!!! Off the shelf parts work if they combo is correct, and you don't even need 10-1 !!

This motor is now going up for sale....its time for the 8's on pump gas...

Very Impressive!!!If i had the money i would seriously consider your motor,with your headers it would bolt right in my car.

Later Mark.

2 Other questions,Are you still using a C-4 and Do you know what the elevation was at the track when you ran the 9.35 pass.

Thanks Mark.

2 Other questions,Are you still using a C-4 and Do you know what the elevation was at the track when you ran the 9.35 pass.

Thanks Mark.


Still the same C4.....works excellent for me now. Track temps were 70-91 degrees...track elevation was 600 ft........DA im not sure, but assume it was at track level or slightly under...I do know at 2500 ft it runs 9.50's...

pm sent

feetfirst,

Thanks for the information what gears are you using in the rearend and is it still a 8.8"?

Thanks Mark.

feetfirst,

Thanks Mark.

Yes, still the same 8.8........and the same 3.27 gears..they have sure held up nice...:)

Even more impressive,3.27 gears in a 8.8" rearend all i have to say is that is a Bad *** ride you have.

Later Mark.

Been following your tread awhile Feet, Im really impressed. I have a very similiar build myself. Im still in the buying parts process and presently in Iraq . I dont have much experience in racing yet so I was wondering what would your car do with a glide in it. I am planning a glide for now but not 100% sold on the idea yet. Also do you think your times would get better if you had more tire. I have the front tires and rims on my car but it didnt come with rears. Thanks for all the info you have given us. Royce

Thanks, Mark.

Very good questions.....as far as the glide, it would be "key" to getting the right stall, much more so than a 3 speed.
I thing once lined out, the glide would be 0.05-0.08 slower.....simply because of the weaker 60 ft factor....

As far as tire, im still running the 28 x 10.5 regular wall at 14 psi....and now looking at some launch pics from the weekend, its time I moved up to the stiff wall.
With a stiff wall comes an even quicker 60 ft, if it sticks.

If you look up at one of those time slips, I ran a mid 80's camaro z-28, fully decked chromoly chassis, tubbed/big tire 14/32.........I think he went a 9.22...1/10 quicker, so it stands to reason his 60 ft would also be a bit better......1.26 to my 1.29 on that pass, but I can promise you it wasnt due to spinning, it was WHERE my car landed at the 60 ft marker.......;)

Just take a look at my 1/8th mile et's on all the slips, that will tell the story on this tire.

Big tire is really not neccessary at this stage, but would help on marginal track conditions...

What little bit the car would slow to the 330 (if any) it would make up for and some from there on out the backdoor.

And yes to converter needs to be right...............:)


My junk never got into the 1.20's until I put the 2 speed in.

Very Impressive!

Interesting how my car and your car run the same 1/8 and 1/4 ET however my short times are 1.37 to 1.39 and my 1/8 mph is 117-ish with 143 to 144mph 1/4. Your car is working the suspension HARD in the first few hundred feet :cool:

We are trying to get the Open Comp class split for NMRA and run a Pro Comp class for cars 8.50 to 9.99

BTW when I switched from a C4 to a glide I picked up ET and mph in the 1/8 and 1/4 while not loosing any short time.

Maybe this winter I'll finally break down and get a tubular front K-member, arms and some adjustable front struts, probably not :rolleyes:

Interesting.........what 1rst gear are you guys running in the glides? Damon, I wouldn't waste money on the front end.....more stall is what you need...:)
The procomp class is a good move, makes it for closer et's, and better racing. These 2 classes are really taking over up here...

1.80

1.76 Straight cut gear with 31" tires and a 4.30 gear. Stall is 5500 WFO on the brake.

1.80 staright cut, w/ 3.73, 28 x 10.5, and a tight 4000 nos convertor 3200lbs --- i leave at 3700 rpm

1.32 60' 5.801 @ 122 9.01 @ 154.6

congrat man, I hope my 502 will make me as happy... hopefully we will see this weekend..

Awesome build ,

Where did your block come from F-350 , or something else and is there any advantage to the older 460's like one out of a lincoln mark 4 as compared to a 90 F-350 I want to build a sprayed pump gas street beater hopefully fast like yours and much uglier since i am low on cash.

and where would you recomend to get a block from ?
Thanks

the blocks are pretty much the same. where are you located at? I have a extra sitting in my garage.

there is no way those numbers are being run with no spray a 327 gear and ur getting that quick i cant belive it.
i would love to see a pic of this motor
that is two dam quick

To come on here with 2 posts and accuse someone is pure jealousy, and a pure lack of knowledge and capabilities.........if you would actually read the info on this site, you may infact be able to REMOVE the spray, and still run just as fast..........happy reading....

jealousy? nope none on this side im just tryin to see how u are running such a fast number and no spray
awesome for u if u really ARE :o
nice motor by the way
and does it really matter if i have 2 post on this site

Well it is all motor, on 91 octane fuel........and this build having the top 3 or so for people viewing at 14,000 +, and then for you to come on here with 2 posts, just seemed a little strange and hit me the wrong way........this is just a little motor, nothing special at all.......with off the shelf parts.......there are lots on here that make 800-900 hp and run mid 5's.......

bignos514, tell us your combo so that someone can help you go that fast with your car on motor. it can be done. i go 6.0s all day with a similar combo be not on pump gas. my car is heavy and all on off the shelf parts, nothing fancy. so do some research before you critisize.

look this is my first big block build i have been around it for a very long time the car im using had a 518 in it the 79 capri green and white im running a 514 11.1 and i think im buying a set of heads and intake off a guy on here i havnt picked my cam yet im using a th400 with trans brake i belive mark told me the car was a 3100 car with him in it ive up graded a few things since ive got it
i just need to figure out what cam im going to run with these heads

Your lucky you didn't get smashed here on this website for your 5 total post and to accuse feetfirst of BS....your pretty brave.....maybe not so much brave...maybe a little crazy bc you aint been here long enough to tell us who you are. You have to earn your stripes here....just like anywhere else...jmho

look i dont know where your going with this whole post thing. here in canada there is not too mlany cars that have the kinda engine setup running those numbers and really it was just really hard to belive. The car i bought off stroker says was running in the 9's with 2 stages of nitrous and a 518 with cj heads thats all whole lot of power than i hear this guy going low 9's with no spray and smaller cid and very low gears

LOOK BIGNOS514 THIS IS JUST WHAT THE GREAT BILLY GLIDDIN TALKS ABOUT! PEOPLE SPENDS ALL THERE MONEY ON HORESPOWER AND DON'T EVEN KNOW HOW TO GET IT DOWN THE TRACK, SO STOP TALKING HOW DID HE GET HIS CAR TO RUN SO FAST! BECAUSE IT CAN BE DONE! SPEND MORE TIME ON YOUR SETUP AND GET ALL THE POWER TO THE GROUND AND YOU TO WILL SEE THE 460'S POWER! AND THAT YOU DON'T REALLY NEED ALL THAT POWER TO GET YOUR ET!

PEOPLE SPENDS ALL THERE MONEY ON HORESPOWER AND DON'T EVEN KNOW HOW TO GET IT DOWN THE TRACK,

That's what it's all about right there...

His car is definitely set up well and runs the number to prove it.

When you said green/white capri.........I knew I had seen that car before.........where are you at?? I'd be more than happy for you to come and look at the car in person, and give you some pointers........:)

i run a performance store here in hamilton where r u from

just a qustion does anyone have videos of these bbf going these numbers on pump gas so i can show some people this

that car leaves ****in hard wow congrats but ive never seen that car wow i really like it

;).......since then I have wittled down the 60 ft another 0.05...;)

Not so hard to believe. These BBF's are Torque MONSTERS!

When I first got my 534 together it was running 6 teens and 9.70's and is now running 5.90's and 9.30's with some tuning and other variables...

yeah but that cubic and low compression motor is still amazing to me...not even 10:1 motor running them times are superb!

I`ve got no problem with those numbers on pump gas with a C4,I use 4.11s with a 32" tire & footbrake in the 1.2s on a good weather day!

Yeah, but your driving a vega.....I know ur stuff aint no 3000+lb

See I think a lot of people get the mis understanding of running in the 9's at 3000lbs on pump gas on motor.....it can be done all day long, but there is a catch to what's considered a perfect combination and if you can figure that out....well, even running high 9's is power made everywhere, but to be running mid to low 9's on motor on 91 octane is by far amazing.

2820 with me in it, it has cast iron heads.

Are these engines happier with more or less gear? The reason I ask is because I went from a 3.55 to a 3.73 and my car seem to have loss some mph and my 60ft went from a best on motor of 1.56 to a 1.55. I'm just looking at Feetfirst times and wondering if a 3.27 might improve my car. I run a 472ci,11.1 cr, dove-c's with 2.19/1.76 and exhaust ported mildly,victor jr,850 holley, forged speedpro's,comp.cams H284XE hyd..584/.588,c-6, TCI Streetfighter Convertor 3200-3500. Car weigh's around 3200 with me. Also, do I need to be working towards a C-4. The C-6 has definitely been maintenance free, but it seems that most of the cars I see with a bigblock run real fast are running C-4's due to the weight savings.

There`s only one way to find out if it wants less gear, some cars pick up, others dont. I barely shift to3rd in the eighth, but thats what my car likes.

Your close to 300 lbs lighter....thats 3 tenths....almost half a second. Do you know what kind of power you need to make up 300 lbs? I think feetfirst car is close to 3100 with him in it...your closer to 2800 lbs.

I haven't weighed it this year, but its around 3050 lbs....

ok feetfirst maybe you can help me I have a pretty close set up but im not running anywhere close to those numbers here goes 89 hatchback 514 aluminum cobra jets 10.3 comp 270-280@50 721 lift 112 lc same intake 1050 dom powerglide 9" bolt together conv 3.73 gears 8.8 rear 28/10.5 tire 3150lbs first pass 1.65 60ft 7.05 1/8 102.29 10.80 @133.14 leaving at 3500 on the brake felt like a turd. Changed stall in converter so it would leave @4800 on the brake 1.55 60ft 6.68@105.66 10.36@134.93 better but still leaves like a turd plugs looked like heat was down a couple threads so took timing down from 37 to 34 1.55 60ft 6.61@107.14 10.26@135.75 so i took 2 more degrees out and lost mph&et so I think 34 is the magic # I did dyno the engine from 4500 to 6500 peak power 726hp@6500 667tq@5000 I also put it on the chassis dyno it made 525hp to the tires what do you see wrong with this? Is the cam way wrong?

Sounds like a good nitrous cam

mach1 your 60 ft is terrible. that is most of your problem. you have a very close set up to me. the cam is not that bad. you may want to check the degree of it to make it run a little better on the bottom end. my cam is similar with a 110 ls. with a little more lift. check your fuel supply make sure the hood is not too close to the carb. i have been 1.38s with the old rear set up with 3.73 and a 1.36 with the 4.10 and old rear set up. i have a new untested rear set up now. 3200 lbs. also check you transmission and convertor. you motor is making good power so i know you can go in the high nines on motor @ 3150, keep at it and someone will help on the board to get it right. thats what i did. had alot of help from the board.

hey any of u engine tech guys wanna give me some advice on the parts to put in my 514 please see my post lets build a motor i could use some ideas im learning bbf and sbf are really different

yea it is a cam i had out of a 557 nos motor i wasnt sure if that could be my problem or not

Im pretty sure the cam came out at the 112 when we set it up.I would advance it to bring in the bottom end right?tranny is fresh and like i said Marty Chance just had the converter apart and bumped it up for me but he didnt want to put anymore in the converter because I will be spraying it later and he didnt want me to drive thru it.Any other help would be appreciated Thank you

Well, this is the problem......you cannot have a nitrous setup run "excellent" on motor......you have to choose to run on nitrous, or on motor......not both.
Running a nitrous setup on motor, will always cost ET, as its not efficient.

I been following this tread for awhile all the way from Iraq. This is really a good post for me since my combo is alot alike to Feetfirst.Well just a observation for Mach 1 . I was comparing power ratings and I see a problem with your numbers. Maybe there correct or maybe something to look at that will help you get better timeslips. Well with the numbers you posted, you are saying there is a 200 hp lose to the wheels. Thats alot of power lost compared to Feetfirst unless you used NOS on the dyno.
Feetfirst 565hp/505 at the wheels 685 hp/615tq estimated only by weight and timeslips
Mach1 525hp/ at the wheels 726 hp/667 tq Dyno
Maybe the cam is causing this or something else under a load. thanks Royce

Power glide/stall set up for Nos, I think.......;)
Yes, there is a RWHP difference, which would explain the difference in performance on the track......its very possible that there is a problem with HP from the engine dyno to the car/track.........have seen it lots of times, and it could be a number of things...but, the MPH is the true teller of HP, and it is close to the RWHP #'s....

feet i know that powerglides and high stalls dont do well on dynos for some reason. my rear wheel hp was close to the same but my car can go 6.0-6.10 in the heat @ 3200lbs. have not ran it in the cool weather yet. has been 139-140 mph in the 1/4 with only 545 rwhp.

no nos was used on the dyno runs but i can tell you this chassis (dyno dynamics) dyno does read a bit low compared to a mustang dyno and with the glide and these converters this is about the norm from what ive seen on loss and we were running on slicks and it seems to always read a little low with them compared to a street tire. I wasnt looking for peak numbers just wanted it close before i headed to the track.The first run was really weak thats why I had them kick up the conv and we were able to leave at 4800 but still only a 1.55 60 ft and I saw where you were leaving at quite a bit lower than that with less gear thats why I was suspecting a cam issue or maybe the 2 speed compared to the 3 speed might be part of the problem just looking for some opinions from the experts Thanks
