That thing looks amazing and I think the coolest part is that your gonna use it for competition and not just a show car.

Thanks Guys ,

the bracket I race in is dial-your-own , so I can pretty much run what I brung.

I had the option of going max effort race with a small block or big block , but decided to stay True To The Blue , and put something on the track that no-one here in WA has seen before ( You reckon Boss engines are few and far between over there , I had never seen one in the flesh until my parts arrived from Kaase , and I have been in drag racing for over 25years now).

This engine combo , race internals with traditional look , will turn heads. It is innovative in many ways , as you cant buy any of the stuff for this engine in boxes . It is one Sh*% load of custom machining and fabrication.

Its going to look the part , now we just need it to make good power 7500RPM - 8000RPM and it will be a low 7 or possibly even a high 6 race car , naturally aspirated.

Fingers crossed.

John

OH, someone get me a bib and a diaper!!! lol As far as exhaust goes, a tuned header will be better matched to a NA set up, more low end torque.....Zoomies, on the other hand, give you that over the top, Altered/Fuel car look. Since you're running a dial of your own choice, as I am in my Rail (and I might just go with a zoomie for my NA motor....just for the look), being down a few horses down low might be acceptable. As a matter of fact, since you're going to be running a three speed, you should be getting quick revs (where a short tube zoomie would work) right out of the hole any way.....Just my 2 cents worth.

Thanks Rob,

it is food for thought. One of our concerns is too much down low with a 2.46 first gear . We were thinking of taking timing out in first gear if we could not control it. I am not adverse to loosing a bit of bottom end for a free-er reving top end.

"Does this chassis make my engine look big?" LOL
Great build brother! Can I ask who built the oil pan?

Thanks

D-Cell,

sure can , the pan was built by My racecar builder . I call Ian Jenkens from JPP a racecar builder in that he does most stuff in house. Not only chassis , but all fabrication for racecars , oil pans , tanks , trans building , electrical , electronics etc etc.

It will be interesting when we get it on the dyno , to have a look at what the oil is doing. This has got three flat trays with a scraper lip on each , and also has two chambers and two gates. I was losing oil pressure on the last engine just after hitting max negative gees when the chutes blossomed in the braking area. The data logger showed it quite clearly that it dropped from 100psi through the traps , rolled off it and we had an rpm related drop to 70-80psi , then chutes and a drop to 30psi. All the oil was in the covers and the valley , with little left in the sump for good pickup. The two gates gates are to try and keep more oil in the rear of the sump around the pickup during shutdown.

The Boss 9 also looks like its going to have drain back problems ( specially when compared to my old A429 ) , so I am going to carry up to 3 gallons ( 12 litres ) initially on the dyno to see how much oil gets pumped into the valley and covers and how bad ( or good ) the drain back is. I use a 30W60 racing oil as I believe big engines need big oil.

The two peice design is so I dont have an excuse not to regularly check the Aluminium rods and bearings. With an O Ring seal and easy to get to fastners , it can be done in a half hour.

Not a cheap oil pan though!!!

Quick Update Guys

Just a quick update for those that might be wondering.

Attached is a couple of photo's. Jenks at JPP has finished the remodelling of all my alternator , oil pump and fuel pump on the front of the motor to suit the Danny Bee and new engine plate. It is all a little more compact now , as the little altered chassis is filling up quick.

Now its just leads and exhausts and off it goes to the Dyno. Anyone know a good set of around the rocker covers leads for this thing. Race Chrysler Hemi leads are too large diameter in the plug tubes, maybe Ford Modular will fit?

Had to order the 2 3/8th 304 stainless u-Bends for the zoomies from Specialty Design Products over there in the US. No one carries that size here , let alone bends it of a 6" radius. They should look cool , as long as they sound good at 7500rpm plus , they should do the trick.

Post again soon,

John

If by "Stick" you mean the bump stick , then it is an aggressive custom Comp , 282/288 @ 50" , 770/740 lift. We have others of various sizes , but considering how good the .300-.600 flow numbers are , its a reasonably safe place to start. The dyno should tell us what the motor wants , and we will get another grind after our first session. Its hard having not played naturally aspirated alcohol hemi's before to figure out what these heads will do/will want. All other hemi's we have played with have all been blown alcohol.

The heads will only take a .800 lift with 20-30th lash ( 770-780 at the valve ) and we did not want to go to the expense of installing longer valves and/or cutting the spring pockets deeper and having to play with the geometry to go higher lift.

Zoomie's Now Mocked Up

The zoomies are taking shape. Also included a more detailed photo of the front package showing alternator, oil pump, fuel pump , crank trigger , injection shutoff and bypasses etc.

Rob,

it sure is tight for room at the front , but turning the alternator around and running it from a pully mounted behind the balancer picked us up a bunch of room.

As for the zoomies , we are going to dyno the engine with a set of borrowed 2 1/4 headers and then swap onto the zoomies for a quick pull to do a back to back comparison ( if the dyno operator doesnt mind the noise ) Could be interesting.

Ouch, my ears! lol You ought to record the sound pressure levels! lol I'll bet you'll lose a few horses across the board over the long tubes. Keep the dyno #'s coming, this ought to be interesting. (I hope the dyno room has wire in the glass!) ;)
