As a user of MSD in the past, one of the main benefits of MSD is lack of plug fouling, and of course a great spark, and from what I have read better ignition means more power!
The other question is reliability for a road race car, I had an MSD 6AL with a dual point Mallory distibutor and blaster coil on my big hp injected Chev- no problems, but I read posts of MSD analogue and digital giving a certain amount of problems, and in race cars having dual ignitions in case one fails - I was about to order MSD but feel they aren't that reliable, and it would be worth having a spare coil that could be wired up, to get you home upon failure.

I dare say that can be said for any ignition system, mind you I have a little Ford Laser (Mazda 1.3) with over 300,000k still going strong on its dist module and coil etc, nothing touched on engine!
