1 Here are the parts and sundries that are going to be used to freshen up the engine’s looks and make it presentable. On the parts side we picked up an air cleaner assembly, chrome hold-down nuts (not shown), and a set of Slant-Edge valve covers from Proform Parts. These parts set us back just over 300 bucks, and the style points alone were worth that. The other key component of the freshen-up is the Rust-Oleum Engine Enamel. We picked up two cans of the satin black and a can of the Cast Coat Iron. This Stops Rust–formula spray paint will resist the engine’s heat up to 500 degrees F, is gas- and oil-resistant, and the can sprays at any angle, making it perfect for this task.
