What is the stock ground on a 351 cam? And thanks for the info Matt. I will definetely stick with this cam until I rebuild the motor again but that will not be for a long time I hope since it's a fairly new motor with around 20,000 miles on it. I got it from an older guy that is a good friend and he helps me out all the time. He upgraded to (my favorite) a 460 and sold me this one.
