I have a question regarding a problem with my 66 Riv, The problem seems to be in mid range performance(1,000 rpm to 4,000 rpm), or the lack there of. So my question was, could it be the ignition curve making it so slow? The dist. is set at about 8 initial , and the curve is stock, i have an MSD box also, What would be a good ignition curve for the car? , It's a 66 Riv 425/ST400 all stock , with 3.91 rear, The car tachs at 3000 Rpm at 60mph with 235/70/15 Tires..
