    I just picked up another boat with a 454 Mag MPI/Procharger set-up w/Aeromotive fuel sys. What plug should I use?

    This brings up a good question, what is everyones preferred gap. I've always assumed that you would tighten up the gap with a blower.

    John, Alot depends on what type of ignition system you are running. With Mags you run the gap at 18-20, with electronic systems (not sure because I don't run them) I would think you would run the gap around 38-40. Just my .02

    Love the avatar Louis

    Thanks for the info. l've heard from some about the smaller gaps also for MSD types systems which is why I posed the question.

    You and Richard racing this year or recovering?

    Lets see, getting thrown under that dash at one circle race and then getting thrown out of the boat at another circle race WASN'T exciting enough for you?
