Let me revise that to around 9.4 HP.

Stan I wouldn't argue anything about machine work with you, but I disagree on the HP needed. Maybe in a lightweight car. But in my 40 plus years of running stockers I'd say more like 15 to 18HP. The point I was going to make if someone can pick up .7 with an intake and heads you must have some pretty bad heads to begin with. Just a few years ago it was 8hp difference with an intake on a small block stocker. If someone is getting much more than that I would love to see it in tec at Indy.
Using the 15 hp number to go .7 you would need to pick up 105hp. That would be 97 hp from head minus the intake. I think I use one of the best out there but if you have someone that can get me 100 hp from a set of heads please let me know. BP
