I want to put the biggest cam in it but still be able to drive it a little, if i jam a big cam in it will i gain anything. How big of a cam can i put in it (500lift) i would probally only put a few hundred miles on it in a year. I mean im not going to put alum heads on it yet ($$$$$$$$$$), but i was thinking about porting and polishing the heads and getting a different intake, headers (converter and gears). And its going in a wagon, its a 1970 455 auto.
