YA Know we have never done a MSD upgrade on a 7.4 EFI so as much as i want to sell you the parts i have to say that i cant honestly tell you that it will work, unless you konw someone who has done this with that motor. I would probably do a little checking into it before you spend the money. when the time is right and if this can be done with no problems i would love to help you out with the parts at the right price. let me know
wow--thanks for the insight. Guess I need to search a little more.
