One more thing that I always do with those base crate 350's: Replace the cheap valve cover gaskets and oil pan gaskets with FEL-PRO perma-dry gaskets (blue rubber), as well as the rear main seal with a FEL-PRO and install it correctly, or they will start leaking within weeks. Gen.I 350's have a bad rep about leaking rear mains (rightfully so) but FEL-PRO took care of that with their perma-dry gaskets , in my opinion. I have installed several over the last few years in different engines and they are still bone dry. I know it's a little more work, but worth it, imo. The people here on the board can help you with how to install it the right way and it's pretty straight forward with the engine on the stand.
