Mopar electronic conversion fires 4 cylinder only

this may not help. but its what my dad came up with to reduce the confusion of wiring single fire V8s.
Mopar single fire V8 dist cap wiring
My dad made this saying about small and big block dist cap wireing. To reduce wiring confuseion. “the small block has the dist in the wrong place, in the back of the engine. BUT the shaft rotates the right way clockwise. The big block has the dist in the right place, in the front of the engine BUT the shaft rotates the wrong direction counterclockwise. Both wire #5 and #7 on both ALL ways have #5 before #7 on the cap AND block. And most / some stock V8s have the fireing order cast in to the intake manifold. And more info: if the cap has a vent hole next to the center tower. Plug it with JB-weld.
