I have a 79 L-82 thats in the shop getting a 700R4, it already has 308 gears. The engine is geting a set of L-31 heads with 1.6 to 1 roller tip rockers. compression should be 10.2 to 1 as best I can guess.The question is what would be a good pic for a cam ? Stock L-82 still in it now should I leave it or maybe go with a EX268H ?? any other advise.
