Rowdy and Mean 318 build

I haven't read all your previous posts. Why not repair the 360? Did you ruin the block? IMO with the intention of turning 6500 rpm, you should be using forged pistons. Probably a solid cam too. I don't quite understand peoples love for hyper pistons. Sure, you can fit them tighter. Big deal. A forged piston, when abused, will deform before it outright fails. A cast/hyper piston will break into pieces.
