    Folks,

    I dont care what blower one has.
    Im trying to figure out which plugs you would use, what gap settings and what brand.
    I got a lonley little 5.7 with the Techco product and I think Im having issues where the blower blowing out the spark.

    If you're using stock coil packs, try a .035 gap.

    With the Vortech kit, we had to go down to .032 with the stock coils until we started using MSD blaster coils. Now I can run mine at .040 without losing spark.

    Plugs - it depends how often you want to change them. I'm running the NGK Iridiums that are 2 steps colder than stock. They now have copper plugs that are also colder than stock and a lot cheaper than the iridiums, but you need to change them more frequently.

    My current plugs are NGK Iridiums 2 steps colder gapped at .44.

    Right now I smell unused fuel and the tips of the plugs are almost redish in color and she spudders like shit.
    Pretty much matches the exhaust pipes. Now you see why I'm asking.

    Definitely close the gap before thinking of new plugs. If you don't mind changing and gapping plugs a few times, try .040. If its still happening, you can go lower.

    Redish?

    Are you using an Octane Booster Additive? If you are, the redish color is normal.

    But yea, go with Adam's suggestion of lowering the gaps.

    No octane boost at all. We will for sure be going back to LA. There may be something else up with her as well.

    Sounds like it's running way fat as well as blowing out spark.
