MSD 6420 6AL
 
I have a 6420 box now and was wondering if the 6425 box would be a good upgrade,have no issues on mine.

Why :?: The 6420 will run anything you have with an added 2 or 3 step. I've run the 6420 on blown alcohol engines and have 2 of them. I also have a 7AL sitting on the shelf which i don't use, because i don't find it necessary.
