No, maybe the 150 pills 63N, 71F, I installed a fresh set of 3924s & the cars back on track 8), I don't think i'll change plugs with even the 150 shot, they seem to be holding up very well as is, i'll just run alittle 110 & take out timing. Like before, when i hit it with the 55N, 63F pills it was specacular on how it felt, & to boot i jetted the carb up with 72/76 jets, it was on the fat side & still made a very clean run, i knew it was overkill but it didn't miss a lick, now i've jetted back to 69/74, about 6% richer then factory, I think my 60fts are back on track too, i'll bet with a few runs it should go a 7.3 @ 95 with the smaller pills & still run on pump gas if i wanted, thats with the timing at 30*. The air is getting much better now around here, falls starting to settle in.
