i have a 1968 - 1976 350 block and 307 heads, intake and 2 barrel carb. I wanted to put some life into the engine with some upgrades. I was wondering what would be the best things to do. It is goin in a 68 chevelle malibu with a th400 and a stage 2 shift kit stock converter and stock 10 bolt rear end. But it does have a hurst pistol grip shifter. I was thinkin of a cam intake carb and headers but im not sure what would be a good combo? I have been looking at summit for parts and found they have cheap cams in their summit packages. If anyone could help me out alittle that would be awsome.
