Hey gurus and car guys! I am currently running champion rj12yc gapped at .035, it seems to work well. Just wondering if I am on the right track or if there is a better plug/gap combo. I've got a 1972 413 with a stock rotating assembly, 284/484 Mopar performance purple cam, 906 heads , a weiand intake,edlebrock 650 carb and a digital MSD 6al. Any input will be appreciated!
