If i were to build a 331 stroker, what else do i neede. If i start with a short block, are there special 331 heads or cams out there that have to be ran? If i have a stock 302 out of a 88 mustang will a 331 kit just go in and automaticaly make more power? Im curious as to how in-depth it would be. Also how do i know what cc pistons to use?
