Re: New to american engines
So your looking to work with what you have on a budget. Heads can be cleaned up and port matched. But do inspect the valve stem heights for sunken seats. Adding hardened seats is a option and can be expensive but cheap core heads can be found if needed. Headers a given. Better intake, carb, cam, lifters and valve springs. I would think about finding a 390 crank, pistons and rods. Your block can easily and safely be bored to 4.05 if it hasn't already. Your truck will like the extra torque and the parts aren't very expensive. Or stick with the 352 setup if it's just not affordable. Where are you located? If your outside of the US shipping can get expensive so that's a factor too. Most of these things can get you the 100+hp. Do you want to do a full rebuild or just add ons?
