Do you know how much power or what Et it would do without the nitrous? Also what compression are you running?

OFF THE BOTTLE IT IS A 10.30 AND IT IS AROUND 128- 132 MPH. I DON'T RUN IT OFF THE BOTTLE TO OFTEN. ONLY IF WE RUN OUT OR IT MALFUNCTIONS. WAS TUNED FOR THE BOTTLE BY MY BUDDY AT HIS SPEED SHOP.
MY PROBLEM IS PLANTING THE 14'S TO THE PAVEMENT WITH OUT IT ROASTING THEM UP!

This really makes me wonder about these heads , There was a huge war that happened over the worth of these heads awhile back . I asked about them and never really got my questions anwered .

Do these heads have there place . Are they capable of 600 plus horsepower level otb with streetable compression and cam or do you need to tailor to them with a lot of compression and huge cam numbers ? I am not trying to hi jack here , it just seems people are throwing out some real numbers now not just saying they are worthless . I still think someone needs to do some otb dyno comparisons and post the results good or bad . If these heads make same or more power than ported DOVE's with big valves I would consider them worth the relatively cheap prices I have seen .

I will probably piss someone off but if they work decent at an affordable price then I would use them , granted I would prefer american made parts but I guess an american company needs to make there heads more affordable .

My HP calculator says it takes 600 HP to take 2875 pounds 10.32 @ 130.4 MPH which gives us a ball park for N/A HP for this combo. With a 200 shot I can see 750 HP out of the combo at the FLYWHEEL.

I will compare this to a truck puller combo done several years ago.

10.6 to 1 545 inch pump gas combo
RHP max effort cj match Doves 350 / 200 max flow
Ported victor intake
1050 dommy
XR292R solid roller cam. 254/260 @ .050 .670" + lift ground on a 108 lobe sep.
comp pro mag rockers
34 degrees total timing
2" header primarys

The above combo made 650+ pound feet of torque and 680 to 690 hp and change. Add some compression and more cam and 700+ would be too easy.

Though the two combos are not exactly the same they have enough in common that it is glaringly apparent to me that the procomp cnc heads fall short when compared to the fully ported iron heads.

I have done wet flow tests on the p/c intake port and the port is messed up. Flow bias is not to the chamber wall side as all other bbf heads are but rather to the exhaust side of the intake bowl. This plays havok with high lift quality of flow and mixture motion and would seem to explain why the castings underperform.

I have been working on a p/c casting I have trying just to reshape the bowl and bias the flow column to the chamber side of the bowl. I have managed to improve the bias significantly however the heads still do not have as good of mixture motion as the others.

I did however realize a significant gain in flow above .600" lift in doing so with: 330 at .600" / 340@ .650" / 351 @ .700" and 366 @ / .800" lift. These flow rates are similar to those i am aware of from another respected member of this board whos ported p/c's were slower in the quarter mile than a worked set of D0VE's. I am going to speak with this individual to get some more specifics and ask if he will chime in. I have been talking with randy malick about these heads to try and figure out a reasonable way with port work to close the gap in the HP numbers.

I have an assembled trw domed short block at my shop. I guess i will just have to build a known good iron headed combo but substitute the p/c heads and see how they stack up.

I have never checked a pair of the cnc procomps for flow rates so i can not vouch for the rates given.

More later...

I have a stock 460 CI with DOVES that goes 9.4-9.6 with a 225 in the big shot plate @3100lbs. So I guess what your saying is that the Pro Comps are within a half a second of well done DOVES if you spot the Pro Comps 85 cubic inches. Im not sayin, Im just sayin.

Thank you Scotty and anyone else who helps answer the question. I have been looking forward to some real hp numbers compared to ported cast iron heads .I bracket race so 1000hp engine would be stupid in my class but 600 makes for some nice et's .

WELL GENTS, DIDN'T MEAN TO GET EVERYBODY IN A HISS!
WHAT I AM SAYING, IF YOU ARE LOOKING FOR A DECENT HEAD FOR THE MONEY. PROCOMP IS NO DIFFERENT THAN ANY OTHER HEAD. THEY ARE NOT AS WELL AS TFS OR EDDIES BUT YOU AREN'T GOING TO PAY $1600-2500 FOR IT EITHER. I PAID $1100 FOR FULLY PORTED CNC HEADS ($850 FOR THE NON CNC) RIGHT OUT OF THE BOX AND SLAPPED THEM ON. PROCOMP ALSO HAS OR HAD A PRETTY GOOD CAST SET OF HEADS WITH RAISED EXHAUST PORTS FOR AROUND($650)THAT FLOW TESTED RIGHT WITH THE STOCK DOVES.
YES, TO GET A MORE CONSISTAINT CAR I WILL HAVE TO FORK OUT THE BIG BUCKS AND GO WITH A SET OF TFS OR EDDIES HEADS. BUT, FOR HAVING A TOTAL OF JUST OVER $4480 INTO MY WHOLE MOTOR SET UP. I THINK THAT FOR THE PRICE PROCOMP IS A GOOD HEAD, NOT GREAT, BUT IT IS A STEP UP FROM THE CAST CRAP THEY CAME WITH AND ABOVE THE DOVE HEADS WITHOUT SPENDING A BUNCH TO PORT THEM, AND THEN WONDERING IF THE SHOP DIDN'T MESS YOUR STUFF UP! PORTING IS NO EASY TASK! IF IT WAS EVERYONE WOULD BE DOING IT!

ALSO FOR THE RANGER GUY! LOOK AT THE ARTICAL MM&FF DID ON THEM A YEAR OR TWO BACK. THIS IS WHAT MADE ME BUY A SET AND RUN THEM.

http://www.musclemustangfastfords.co...est/index.html

PROCOMP WHEN THEY FIRST CAME OUT THEY HAD A LOT OF PROBLEMS WITH THERE HEADS. JUST LIKE MOST COMPANIES DO! BUT, THEY CORRECTED THEM AND HAVE BEEN PUTTING OUT A GOOD PRODUCT! THEY ARE GOING TO BE AN UP AND COMING COMPANY IN THE PREFORMANCE WORLD!

MY OPINION!

545 STROKER KIT FROM CNC $1200
H BEAMS, FORGED CRANK, KEITH BLACK -3cc FLAT TOP PISTONS

SPLAYED MAINS $120
STUD GIRDEL $100
CAM AND LIFTERS $110
TIMING CHAIN AND COVER $105
COOPER HEAD GASKETS $90
PROCOMP CNC HEADS $1100
1.73 ROLLER ROCKERS $139
PUSH RODS $45
MAINFOLD $275
1050 DOM $750 NEW FACTORY REMAN
PROCOMP HEI DIST.W/ WIRERS 9MM $105
FELPRO GASKETS SET $55
USED MOROSO OIL PAN $ 56
VALVE COVER USED MOTORSPORTS $20
STAINLESS BOLT KIT $30
HEAD STUD KIT ARP & MAINS STUDS $180

They arent above DOVES when my stock 460 will outrun your 545 with procomps.

460 out of 92 F250 rings and bearings.
Home poerted DOVES
ported Edelbrock Victor
Pro Systems 1050
Harland Sharp Rockers
Comp solid flat tappet
Hooker headers
NOS big shot plate
MSD dist.

My motor is STOCK with good fasteners, cam, intake and carb, and is a tick away from going in the 8s. So to me Pro Comps arent that good of a bang for the buck. By the time you mess with cheap castings and put good hardware in them you could buy a set of SCJ, TFS, Edelbrock, Blue Thunder, You name it.

I wasn't trying to stir up an old fued I was just asking for some real numbers with a street/strip engine that runs on pump gas . Cant we all just get along . We are all here for the same purpose to learn from others successes and failures .

Here is what I would think would be a good s/s short block for example ;

.030 over 460 block (you pick the year block)

10-10.5:1 compression with 77 cc heads balanced stock crank and rods

Hi volume oil pump

DOuble roller timing set

A cam similar to the C460 244/254@.050 595/621 lift

A Wiend Stealth or Performer RPM intake

A QFT Q-series 950 carb or equivalent


MSD 8580 ( recurved to the engine combo )

Now that we have a base shortblock which is gonna make better hp/tq ported big valve DOVE's or the out of the box ProComps?

DOVES all day long. Doves have a smaller CC versus the Pro Comps. The Pro combs will be much lower CR than the Doves out of the box, and without work on the Pro Comps they will definitely be down on power.

MY OPINION!

545 STROKER KIT FROM CNC $1200
H BEAMS, FORGED CRANK, KEITH BLACK -3cc FLAT TOP PISTONS

SPLAYED MAINS $120
STUD GIRDEL $100
CAM AND LIFTERS $110
TIMING CHAIN AND COVER $105
COOPER HEAD GASKETS $90
PROCOMP CNC HEADS $1100
1.73 ROLLER ROCKERS $139
PUSH RODS $45
MAINFOLD $275
1050 DOM $750 NEW FACTORY REMAN
PROCOMP HEI DIST.W/ WIRERS 9MM $105
FELPRO GASKETS SET $55
USED MOROSO OIL PAN $ 56
VALVE COVER USED MOTORSPORTS $20
STAINLESS BOLT KIT $30
HEAD STUD KIT ARP & MAINS STUDS $180

Most everyone is on a budget of some sort. Your point is well taken and it seems your happy with your motor and thats all that really matters. You said splayed caps on your motor. Did you convert your block to 4 bolt caps? Unless you do all your own machine work and you do have 4 bolt mains, I'd say you'd still have close to 6 grand plus in your motor. I'm not trying to be knit picky, but the point I'm trying to make is that because of your decision to go with the procomps (fully ported) your kinda maxed out now. You could put a roller in it but you'd need new valves,springs,retainers,stud girdle,etc.
When I did my stroker motor I needed a head that had the exhaust in the same spot as a dove because of my header clearence. Now thats not a problem as I put a rack on the car but I'm stuck with the Eddy's and in reality that somewhat dictates the potential of my motor. When I did my motor over 3 years ago it seemed the only option for me. Now, today there are heads avalible that would of given me more room to expand the potential of my motor. Thats really the point of my reply. If you already have put $6000 plus in a motor, why not put a set of heads on with no porting that will give you the same HP or more then a set of fully ported P/C's for a extra $500 or $600 and have the potential in the future of an easy 100 plus HP because of a superior port design, especialy on a stroker motor that would luv 400+ cfm on the intakes. Just MO.
