318 Senior Project Build

I don't think you're gonna be able to zero deck your block with those stock replacement pistons. With those pistons you won't gain much compression even milling those magnum heads. With that said a comp 268 cam might be a little better performance wise because I think that 280 will be too much cam with stock compression. I could be wrong though, someone else may chime in and either confirm or deny what I said.

Either way, awesome project man!!!!!!
