I am going to upgrade the cam in my LM-1 350 for a little more performance. I would really like to keep the motor all GM, but will consider after market. Will I get more out of an L-82 or a 268H Comp cam? I don't want it too radical. Any suguestions?

I don't recall the specs on the L-82 cam, but the Comp HE268 is a proven performer, and a very street worthy camshaft. Good luck with your decision.
