In one of my cars over the course of a decade I ran a Jacobs, Mallory, Crane, and MSD. Net result is that there is not enough of a difference between well set up versions of any of these to really make a comparison. Speed and e.t. between them all was not significant enough to say any one of them was superior. The driver is a bigger variable to the equation.



I don't think there would be any appreciable difference from one to the other, my goal is simply to replace a malfunctioning unit so I was interested in the durability of other units, I have purchased a crane box from a member here so I guess time will tell if it is better or not.
I do appreciate all of the responses, you guys are great!!
