Has anyone out there made 2 hp/cu in. with a stock block normally aspirated Pontiac on race gas? Or with an aftermarket block? Documented (dyno sheets)?

[harry k]

at what cubic inches ar we talkin?/

[rumair]

i'm pretty sure rex is the first and only to do it na...

[fastgoat]

Because it's hp per cube the size is not the issue. For argument's sake- 400 cubes and up.

[Bud Lyons]

Scott Rex and Jack Gaydosh are a good start for the list. Bruce Machaile(sp) maybe John Langer.

Aren't they all over on the best for 2004 post.

[fastgoat]

None are on the 2004 list nor should they be because the list I see posted on this site are either blown, nitrous, alcohol, turbos, or any combnation of the above.

[Steve C.]

900+ hp on the motor would be a tuff nut with a traditional (modified/expensive) factory block.

Scott Rex is the only one I know thats made 2hp/cid on motor and he is in the fastest list at 7.68

I don't know a lot about Bruce and the others mentioned combos, they may have done it also.

It's sure to be a very short list.

dave johnson comes to mind and harry rienhold were getting close to 2 hp with the stock block.

[fastgoat]

I certainly don't know either Dave Johnson or Harry Rienhold personally but I've seen both cars in Indian Adventure ads, and while both might be making more power since then, at the time both were using that block,which must assume made more power per cube than the stock block. Johnson made 841 hp @ 446 cu in (would need 892 hp for 2.0). Rick Johnson, who built the engines and eventually bought Reinhold's car, made 792 hp @ 427 cu in (would need 854 hp for 2.0)
So unless Rex Scott's 517 makes 1034 hp the answer is either one or none.

Eric Johnson,John Langer and myself have each built NA engines that approached 2HP/CU In.My engine,which was my own design was 446 " and dyno'd 3 years ago at 841 hp [corrected] Eric and John's engines were larger,in the 468-470 cu in range and made more power.
All three of our engines utilized Wentzler Series 1 or 2 cylinder heads. All 3 of the cars dipped into the 8's at roughly 6.9 lbs /cu. in and approx 150 mph,or so in over 3000# cars.
All three used IA blocks and billet cranks,Titanium valves and stiff cams.
I figure I was making at least 1.95 hp/cu in last year. 2 hp/cu/cu in may have been feasible but with huge costs. With a smaller engine it would have been accomplished.The cylinder heads,of coures are the limiting factor and the Wentzler Series 1 and 2 heads are limited in intake flow to about 360 cfm, without reducing the exhaust flow,which is counterproductive.

[John Langer]

Last year I made 1.94 hp/cid, this year I am crossing my fingers for 1.98. I couldn't even imagine 2 hp/cid with series 2 heads without any welding or epoxy.

Hey Dave, I notice you are in Downers Grove. Know a "Tom Kramer" by any chance? He must be around 60 by now.

[samssuperpro]

The best I could get so far is 740 out of my 455 but I've got a few tricks up my sleeve for 2005

In 1986 we did this with a stock block iron headed d-port engine EFI engine 406 but was not on gas.
This engine made 812 at 7500.
