What ignition system will do me justice??

Most of the serious guys I know (granted, they are all old school) say multi-spark units are all hype. As someone else said, the multi-spark stops before you really start making power anyway. It may help a little with cruising MPG but for max power and acceleration it really doesn't work any better than a correctly set up MOPAR system. As I said in an earlier post, I have had my MOPAR system in place since the late 80's so I will most likely stick with MOPAR stuff.
