Pump gas eddie headed 451? Pushing 800 horsepower? I say b.s.
Okay, that is understandable. As I look at it, I did make a mistake. This dyno run shows a beginning of 4,000 rpm, my apologies. I can produce other dyno sheets of 3,100-7,200 with torque above 500 lb-ft from 3,500-7,200 rpm and peaks over 600 lb-ft.
The engine ran in the 2009 Mopar Muscle Magazine Engine Challenge at 600 rpm/sec (less load on the engine) and pulling a mechanical water pump. On an exhibition run after the Challenge, it made 726 HP @ 7,600 RPM and 723.4 HP @ 7,000 RPM during the Challenge. See the May, 2010 issue for a brief build description.
The pull below was months later at 300 rpm/sec with an electric waterpump and with a better air inlet to the carburetor. At Comp Cams, during the Challenge, there was no air hat on the carburetor and the air was swirling around the dyno room like crazy. Also on this run we were using a different cam with a little less duration and a little more lift.
We made 18 dyno runs this session with various headers, tunes and loads on the engine and never made less than 743 HP and 13 runs over 770 HP.
The dyno is no longer a Childress dyno, but is owned and run by Aldon Miller of Performance Machine, Idaho Falls, ID. They just never could get the computer to change the heading.

Stir away!
They really are pretty good heads. On Comp Cam's dyno, everyone had to run the RPM heads. The only engine to beat us was 48 ci bigger. He beat us by 1.1 horsepower, 724.5 HP to 723.4 HP.
The Performance Machine dyno sits at 4,700' elevation, so that D.A. is very possible.
The next time I get a big hp/ci motor together, I'll announce it. We'll stand and deliver that baby, heads up, anywhere.

That is a possibility.
But normal D.A.? Gotta laugh at that one. Normal here is 6000+. You guys are the abnormal ones.
Comp is at 258' elevation and the correction factor should be much less. If the iron headed motor hadn't got toasted at Comp Cams this year (they don't run long if you forget the water), we could have taken it to the I.F. dyno and checked that theory out.
Tough to race dynos.

It's a real shame what happened to your motor, it's always nice to see these numbers translated to track figures, Brett Miller's car is turning some good times and sounds real sharp, it's quite amazing how much power some of these small blocks produce and with a lot less weight in the right place.
