Distributor rotor and cap

Instead of looking at cap/rotor clearance which is still a big part of the picture //more energy from the coil is good. But what helped me was a good set of plug wires and some will say they are VOO+DOO but a set of E3 plugs WOKE My car UP !!!!! A NOTICEABLE difference... could be the combination BUT I AM HAPPY

mildly warmed over 340/auto/factory avs carb/pertronix conversation on the dual point prestolite with their matching coil
