    Autolite 3922 gapped at .035. The 23's are for cast iron heads.

    Why am I running 3923's?? Got to ask Eric about that. Maybe that is part of the reason I blew it up. :(

    150 shot isn't that big, 1 range cooler should be enough. TF recommends 3924's, and I use the 3923. Those 3922's must be hard to find as I've never noticed them when buying plugs.

    I have been working hard. Got to finance my addiction. :D
    Trying to decide what motor I will put in my coup. Matt whose blue coup is on Eric's website? Looks like a drag radial car.
