LOL. I've seen a few toenails that could probably gap a .050 plug.
My 54 had a 324 originally. I ran across a J2 engine with the three 2-barrel setup but couldn't afford it at the time. I later installed a 64 425, bored .030, cammed, Offenhauser heads, dual exhausts with lake plugs, and the twin AFB's. Replaced the traction bars practically every week after a night at Forsyth, Dallas, or Yellow River. An occasional driveshaft and transmission, too.
