I couldn't remember. The shop I used to work for was going to attempt to be in the engine build everyone is talking about, but the economy fell out from under it and my ex employer got a real case of the a$$. I only got to play with the ports a little bit, but initial testing with a max wedge port and 2.250 valve netted 345 cfm max. I couldn't remember how much of the seat contained the valve or not as we had intended on installing different seats and running a 55 degree valve job to increase the mid and high lift flow. I really think I could have exceeded 350 cfm but I had to work on jobs that paid. Those heads are probably sitting on a shelf still if he didn't throw them in the scrap...

I don't think the 2.19 valves will do ANYTHING.

......but HELP.

I put 2.25 intakes in my Edelbrock Performer RPM heads and they flowed 341 cfm @ .700". The little 451 stroker made 534.9 lb-ft of torque @ 3,500 rpm, 574.0 lb-ft @ 7,200 rpm and 786.9 HP. Oh......all motor, 11.7:1 on 93 octane (the 10% ethanol stuff). Runs fine on 91 octane too.

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.

not trying to stir the pot but your motor at 7200 made 600 hp actual and corrected to 786,, 186 hp in correction? is that dyno at 6000-7000ft d.a.? is it possible to get that high?

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.

Does it say B.P of 25.02?

Yes it does 25.02. The test run on the dyno from SuperFlow, before it was delivered to Childress, shows the pressure as 24.81 at SuperFlow on the day of the test. SuperFlow is about 5,280' elevation. The dyno program requires the Current Station Pressure. If we call the airport and ask for the pressure they alway give us something in the 28.blahblah until we ask for the Current Station Pressure. At the dyno in I.F. The lowest reading we've seen is 24.32 and the highest in a long while is 25.72.

i wouldnt argue your numbers at 780 or whatever,, just maybe when you bring it down to a normal d.a. it wont do the same thing,, like the correction over compensates for it with how it will perform at the different conditions

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.
