Its time for me to do my first big block build, and just wanted to get some opinions from people here. I'm aiming for 500 horse, but that's not a firm number. I'd like to drive the thing somewhat regularly so I'd like to keep compression between 10-10.5:1, no wild cams. I figure aluminum heads would help matters as well (which ones though). I know this shouldn't be too hard, but I don't want to end up with a bunch of mismatched parts.
