Silly questions: Does lower plug/ wire resistance mean more/better spark? Is reduced radio interference the (only?) reason for higher resistance? For an old V8 car with dual points & no radio, what are the best performance wires & plugs y'all have used? I ask these questions for 2 applications. One, a 413, the other a 392. I wondered if they'd run better with different wires/plugs. Many thanks & happy Spring. mv ----
