Has anyone tried these, or thinks it would be a benefit to our cars. I've always wondered about the stock ignition systems on these cars, and a way to make it more powerful. Back in the day, a better coil, distributor, etc would seem to make a slight difference in performance. I used to use Jacobs Electronics on my Mustang, it was a pretty nice system, but I'm not sure if I really felt any power gain. Would a fatter spark on our cars help with power output?
