Okay I put a 302 in my 86 four eye and I had to go w/ a 4 barrel carb and mechanical distributer. what I was wondering is what should the spark plug gap be for my distributer?? My Stang has a minor miss and I thinl this is the problem cause the plugs came out of a 302 F.I.

what kind of dizzy and ignition are you running? what kind of plugs are you supposed to be running?

all the duraspark/TFI systems can jump a pretty wide gap, i've always gapped mine at 0.045"...some aftermarket systems recommend a slightly smaller or larger gap dependant on coil voltage and spark energy

What heads/ignition are you running?

87+ stuff gets gapped at 0.054"

I beleive 79-86 is gapped at 0.045"

'85 might be a 0.054" year...unsure.
