[QUOTE=Billy Nees;656529]Barry, how much did all of these modern changes raise the peak RPM potential of your combo? That and the "enhanced" heads and intake is where all of the gains are being made.
Just an FYI, you seem to be assuming that all of my stuff is 30 years old. The Pontiac and the Gold Nova have state-of-the-art short blocks and valvetrains in them.

As for the "modernizing" that Doug is trying out, we'll see. I wish him luck and would like to have come talk to me at a race. I have some cheap things he could try that might help.
Billy the heads and intake are pretty good right from the factory. Not long ago we sleeved a 454 to make the 396's. Now with the use of an aftermarket block it had made more hp. The new rings have helped a bunch. Brian has played with many cam grinds. The carbs are better. It is a combo of everything. I can tell you it's at least 3 tenth quicker than my last big block car. Also, in that time they came out with piston, rod, and ring weighs. A lot of engine builders were able to lighten up the rotating rates based on the new numbers. The tranys and converters are better. I don't know how anyone can look at this and say the AHFS should stay the same. Billy we are going to race our cars the way we both want to, but I'd bet if you had a possible of heads up a couple of times a race you would put more effort and money into go faster. BP

PS Billy I'm going to South Beach on Tuesday how about we call a truce until I get back.
