Complete rebuild on a 440, I need suggestions

All you need is a cam and no new hard parts but pistons and cam. NO need to go crazy for that level. I wouldnt keep that compresion goal in mind either. Run a flat top just below (.010-.020) deck, I'd go KB Hyper myself not knowing your Dad. Have the lower end mcahined well, and either do the heads up right or buy some new aluminum ones for more $$. With a mid size cam you'll be at or above your 450hp on pump fuel.
