So late 80's TBI vs 70's-80's Carb Old HEI coil on cap vs points vs newer HEI coil separate from cap. Basically the same vs heat range? or are there different recommended for each specific type.
My 89 calls for the CR43TS seem to fine I'm running them at .040 gap cause I read that was better than .035??? Gap has been all over the place and heat range from what I have read.
.035-.060
