Jody,
Those numbers weren't on the stock block were they? Did you go with a Kenne Bell? My hp and tq goals on the stock motor (maybe with a KB on it) are 475/575. If I go any higher, I want to have a built shortblock waiting for it in the garage for when the stock one lets go.
Beautiful truck by the way. Sonic Blue is an awesome color. Cosmetically I'm planning on either a set or 20" or 22" Forgelines or DPE's, billet grills, painted tonneau cover w/ducktail spoiler, and a roll pan. It's still a little ways off though, so plans may change.
