Alright, so the truck's getting a 440. I'm gonna get a used one and rebuild it. I've heard the stock manifolds flow just as good as the aftermarket ones. Heads I'll have a valve job done on. Camshaft will probably be the RV cam that I've read about on this site. What I'm wondering is are there any relatively cheap rebuild secrets on the 440 that I don't know about? I'm not going to stroke this engine or anything, but little things I can do before I slap it back together are greatly appreciated!! Thanks guys.
