In addition to everything above, replace everything that is made of rubber that has fluids or vacuum. There are rubber hoses at each end of the fuel lines, may wan't to change the sock on the gas tank sending unit while you have the tank out. Before you hit the road, go through the brake system, and replace the fluid (brake fluid adsorbs water). Check the metal brake and full lines for leaks. Agree that Ames is good, as well as Performance years, stay away from Year One, way expensive. FWI, Pontiac engines are not refered to as big block or small block (also the distributer runs CCW).
