I got tired of the stock mopar underhood electrics about 5 years ago so I have been running a chebby one wire alt., blaster 2, and a chebby 4 pin hei unit. I haven't had any problems at all. It runs great Im just getting that itch to change things again. I think that I will do the MSD swap as soon as I get the extra funds and find a good deal on the dist. and box.
