YOUR THE MAN!!! Thanks a ton!
Yes, Chad told me they had the car running 10.50s with a 1050 on it... right now I have a 950 HP that we just started tuning on before the winter break. It has a little too much thrust bearing walk for my taste and they couldn't remember the exact cam specs. So I'll get bearings and rings put in and some new valve springs after I find out what cam I have.
Plan on putting a small plate kit on it and have as much fun as possible.
Thanks again for looking into these heads!
your Heads are probably around 265 CFM ??
i'll keep looking ... i remember seeing Scott's Flow Sheet
by accident going thru other searching for another Flow Sheet
