What compression should I build my 440 stroker too? I'm going to use a 440source.com kit with pistons 30 over and a 4.15 stroke. The goal is streetable motor with 452 heads ported, that will look stock and be able to run fast class. I'll run it on pump gas. - it'll have a 178 intake manifold, which will be ported, stock exhaust manifolds, and a Carter AVC carb. Thanks in advance for your suggestions!
