The 800 HP oval port 11.5 compression engine has not been down the track yet, my customer will have runs on it coming up this spring. To me, I like to know the (racing background) of the people questioning my dyno numbers. So I think its only fair I state my background. I machine and build and test my own engines, everything is machined in house with the crankshaft as an exception. 1. Two strait hot street championships (550 inch NA 10 inch tire 3350 pounds) both ends of the records, won every race except for 1 over a two season span, as an engine builder. 2. The fastest full weight, small tire, oval port (GM) production blocked chevelles in country come out of my shop. 3. Just for you I have an example of a Vortecpro powered 468 NA camaro, I think you just might be able to identify with. NA 468 9.40 @ 142.40 1.28 60 on the foot brake @ 1670 feet DA @ KCIR. BTW on that dyno you questioned the HP of, it made (the 468) 45 less hp than yours, 795 HP. Happy reading:metal:

Dont get in your defensive mode..Sounds like you have had some fast cars,you never know when a keyboard racer is just bumping there gums.

I have had friends show me dyno sheets with big numbers and the car wouldnt run anywhere close to the number it should have.

Thanks for the compliment on my old camaro, I had a 582 bbc,13.5-1 comp,cfe 385 bmf heads,single carb, N/A that dyno'd 1133 H.P built for that car and never got to put it in. That would have been fun !! One of these days I am going to build another hot rod and I may look you up for a powerplant. Geary

I dyno here but it is a rear wheel dyno for harleys. I have a question on the AFR that is showing on the sheet. Is there a reason that its running so rich?? Or was that where they set it as it made the most power there, or ran cooler, Most will run in the 13.0 range to 13.5 and run cool to make the best power.. Not stirring the pot only asking. To me that seems too rich.

It was rich, ever here the saying "leavin a little in the bank"?

Just an FYI.

On the.9.56 pass and the pass with the maroon camaro with the 468. I was there for both of those passes as we rented the track. None of this is bull****.
The 9.56 was off the trailer and the 3rd pass ever on the motor. He also pedal'd that pass because the wheelie went a little higher than he wanted.
Garrets 468 is a bad little mofo!
The red chevelle should go high 20's low 30's when ironed out.
