    I agree with Dave at the 600 mJ also.

    THANK YOU Mike and Dave (20 amp MSD)

    THANKS for the reply and do you think the 20 amp MSD mag will keep all cylinders lit with 4o to 42#s of boost? THANK YOU again for your replies!

    No problems at 40 + lbs of boost with a mag 20 . Have even tried a 44 amp set up with no gains other than running a few degrees less timing .

    In '97 we made 1430 HP using a Mallory Super mag III.
    Mid to high 30's for boost. We probably were leaving some HP on the table but we were competitive on the track.
