Very true! But with the proper research a good choice can be made.

Ours does not fit exactly for combinations asked for here but the 526 we built for Johns's car made 928.9 hp at 7300 rpm with a BOP intake (920.4 w/ Victor), and this was 11-12 years ago. But to my point here for interest and regarding the comment about finding the right people. Our engine was done by a local engine builder here in town that on occasions does a few Pontiac's. A small but complete shop for all except crank work and align hone, he farms that out. And the High Port heads I bought as raw castings were ported by a fellow named Rick McConathy in Houston known for work on Chevy cylinder heads for Texas Pro Stock. He had never seen a set of HP heads before.

Steve,
He may not have seen a Pontiac HP head before that, but over the years slick rick racing heads has turned out some great work.

Pardon me, And Dragncar was asking me the same thing in a PM.
I assumed that my post would give a bit of credit to Richard along the way.

And to add a bit of humor.... about 17 years ago the fellow that did a set of Edelbrock heads for me that supported 700 hp at 7000 rpm owned and ran a BMX bicycle shop. He had never seen a pair before.

I understand exactly what Calvin is saying but with bigger bore space and bigger cubic inches it's easier to throw parts together and make 1.5-1.8hp per CI..
As for the RPM's on a Pontiac I agree with Slowbird....I know for 100% FACT My family has turned our Pontiac bracket motors to 6900-7200rpm through the traps for over 19 yrs wo issues (with 4 diff cars)did it for so long I'd feel pretty confident to say going through at 7500 would still be a "safe rpm" where not to many oil system modifications would need to be done other than maybe a good oil pump.


My current motor is only a 12.5:1 motor with .800 lift that doesn't have a very aggressive lobe......but is 615 cubic inches.
It barely made 1000hp at 6100
But was dyno'd with C15 due to it's consistency....
Therefore I could still think like a traditional Pontiac guy
Maybe I should get ahold of of the guy that said he could make some adapters so I could put some stock 1969 Pontiac valve covers on it..

People switch to Chevy for the cost.

Also because it's easier to get things done in the Chevy world.

How many passes a year do you run?

And on a BBC with nitrous use it's not as easy to lift a head gasket Much better head retention with the Chevy.

You need to get a PONTIAC back in that thing. Its WAY TOO PRETTY for knuckle dragging BBC.
Call up Marcella and have him run a set of High Ports through his 462cfm CNC program, a little work on a BOP, Scott to cam it and you can have 1000 HP of pure PONTIAC back in your ride.
Might be a little more cam than .800, but still very reliable.

[Dragncar]

I was asking Brian if those slips were his. The middle one 1195 HP @ 8300 is impressive, they all are.
I dont mind hearing the particulars of Richards engine. The 79WS6 I would like to finish, I have been thinking about a 500HP "440" that looks stock. But a mild 800HP boosted engine does seem cool.

Mine is off topic for sure, but here are the current details.
IA2 block 4.35x4.35 bore and stroke, 10 to 1 compression, Wide port heads ported by Dave Bisschop, flow around 360CFM I think, 55mm cam with .904 lifters (morel) .265/.277 at .050 .706 lift with 1.5 Rockers. Super victor intake with Megasquirts MS3pro fuel injection. Procharger F1C with 10PSI boost. Car weighs 4000lbs RXT twin clutch connects the T56 Magnum to the engine...best to date is in my signature. I drive it with the belt off, get 16-17MPG. This year I put on about 15000Miles!

[Tom Vaught]

I knew you drove it with the belt off (as did many Ford Racers ago who traveled to racing events) but was waiting for YOU to post that vs people complaining about the belt not being on all the time. You did good Richard and the 517 All Pontiac Block seems to be doing the job for you, as expected.

Yeah I just don't see the point in spinning the procharger all the time, 700HP on the street gets the job done quite nicely, then throw the belt on and let er rip!

Thats awesome, whole new way of looking at it. You can do a LOT of different things with a combo such as yours.

I wonder if its crazy, but is it possible to make some sort of "clutch" like a AC compressor uses for a centrifugal blower. Now THAT would be truly the best of both worlds. Have your cake and eat it too.

Sort of like that old "Mad Max" scene where the guy hits the switch and the roots blower starts turning. We know it was BS in the movie, but could it work with a F1?

Agree, with the blower on the engine and spinning, basically you would just be dumping more air out of the By-pass Valve at normal cruising speeds and wasting fuel driving the blower to pump ambient air from the blower back to atmosphere under the hood.

A/C Clutch would never have the capacity to hold the power of the engine driving the supercharger. Movies vs reality. Magnetic Particle Clutches were looked at by my company for our Hydrogen Bus program. Durability was poor with the systems and you needed a LARGE magnetic particle clutch on the driven pulley (which was like having a flywheel on the supercharger snout). Been there, done that. (The parts are expensive too).

Thanks for the compliment on the car!
I've ran a Pontiac motor with close to .900 lift for a while...
As for Mr. Magic man Marcella I attempted to go that route with him once upon a time 5yrs ago and for one reason or another it wasn't in the cards and that was when I had the money to spend. After meeting John at Norwalk this past year he's a stand up guy and I have always thought he does insane awesome work and the most impressive thing to me,about John is he is a racer himself and UNDERSTANDS his customers want to be out racing instead of waiting on this that or another...I don't take him as a procrastinator due to the amount work he cranks out,and the amount of folks using his products.
Scott.....stand up guy without a doubt! A tremendous help to ANYONES program!!!
But really I'm completely happy with what I have now and am enjoying working with the other parts of racing instead whatever Pontiac update I think I need year after year after year....the plan is to keep this thing in the old beast and just keep logging runs and downloading runs.....
Also the plan is to continue to work with my 72yr old dad on making his car go faster and faster and help him reach his goal of racing longer than the Greek!
That's where I have the most fun at the track is with the old man.

[Gary H]

Don't know how to post it, and really don't have time to troubleshoot how to do it right now, but my new engine made 1029 hp at 7000 rpm, peak torque was 803 at 6100. 541" with wideport Edelbrocks, Gustram cast intake
