What would be the default build for a 450HP 360? Trying to keep the stock bottom end. Can this be done with heads intake cam etc? Never built an engine before and I'm looking for very low 13s to high 12s in my Land Yacht (79 Doba) I'm swapping in an 8 3/4 with 3:91s. Just looking for Ideas and where to start. A buddy is giving me a set of magnum heads. I was thinking Heads, a mild cam, air gap intake, 670 holley, headers, and maybe a little spray would get me somewhat near my goal. I know Cordobas are heavy but from what I've heard 79s are the lightest and mine is a stripper. Its even radio delete. What do you guys think? I'm on a budget and I really dont want to touch the bottom end because if I go that far I might as well get a stroker kit and go that route.
