Ok Heres another question, On my 302 is their another mechanical cam that is better? It does not have to be factory, but I still want the rough dont mess with me idle. With todays tech I would think there would be. Also what a bout todays gas? What should be run? What about lead for the valves? I have petronix ignitor for it but before I paint it I want all the mechanicals finished. Since my budget is very small I want toget it right the first time.
