Bill, Thanks!, I am using the 12370850 new GM Block (from 2007 I think) Your plan looks awesome, but I don't think I need to go as "Far" as you due to budget constraints. I was thinking the 4.25 bore and either the GM 3.76 for 427 or a 4.25 stroke for a 481. either ones with a 163 intake and Holley/ headers. Heads are the biggie info wise and also piston selection. I may just copy your build specs for a 450/500hp street engine. That's all I need. Thanks for keeping me in mind. That is one gorgeous NOVA!
Scott
