i have a blaster HVC coil #8252 and i don't know which MSD ignition to buy.. i have a mildly modified 94 cobra which is mainly a high performance street car which sees the track about once a month.. i don't know whether to go with the Digitial 6 PLUS or the HVC 6 Professional ignition?? whats the difference and which one makes more horses??
p.s. the price difference doesn't matter
