400 to 512 Build

Thanks Green and yeah buddy, that would kick butt.

I'm shooting for 650hp here in the rare air. This build could do 725 or better in good air with a more agressive timing curve. ASSUMING I even hit 650..... we shall see....

I like those HP numbers... I'll be racing down south in good air at an outlaw track.. One part at a time but I'll get there.. I'd have to spend a crap load of cash anyway to reach the performance level I want out of the 383 so why not just spend a little more and go BIG...
