    Novice question, but what plug gap with NGK 3442's, Mallory SMIV (7amps), blown alky BBC. Right now 15 psi boost, once we get the car sorted out, 25 psi.
    I ran .020" gap with my small block, but that was with a low current MSD7AL igniiton system.

    Thanks,
    Keith

    Thats a NGK R5673A-9 and a .018-.019 will work fine.
