I'm sure there are a few.

Anyone willing to post a dyno sheet where the engine made 1000 HP @ 7000RPM?

Calvin,
Chris posted this a few years ago. Not exactly what you wanted.

Marcella dyno sheet:

I got 1052 @ 7000.

If you spend wisely and spend it with the right people it wouldn't be terribly hard to do.

Curt,
Do not know what the dyno correction factor was. But if the 5 column is fuel? You should have some very nice BSFC numbers what ever it was.

Mr Geise, you had a true 1000 hp at 7000 rpm but the other posted dyno sheets were close (not quite there at exactly 7000 rpm)
but made the 1000 hp a couple of hundred rpm higher. Close enough for me. Good job for all who posted their numbers.

Not as easy as you think finding the right people that is!

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.

Deep pockets to have that kinda power lol out of my budget lol

[cgeise]

its been a while -- I don't remember

[slowbird]

A few here, all made well over 1000hp in upper rpm range

All those yours ? The second one is very impressive. Was the top number peak HP ?

Don't know who's dyno sheets they are. But the left one sure looks like it is a cropped John Marcella's sheet from Barry's dyno (Survival Motorsports).

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..

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.
