Hey,
I just changed the intake manifold and carburetor from 2 barrel to 4 barrel q-jet. My 76 has a 350 in it and stock ignition (hei), What gap should i go for the plugs?.. nothing special about them either

Stock HEI should have .45 points use a .35 or that is the way I understand it. It can depend on your head selection also. Sock heads then no big deal. Aluminum heads and also the plugs for some aftermarket heads may be hotter than stock with a different gap.

My HEI is gaped at .45
