plan on changing plugs in my truck this weekend and was wondering what ya thought would be my best bet .. A429 head, 514, msd pro billet dizzy, 6al box, blaster 2 coil, taylor wires..

motor is 9.8:1 comp, 90% street use, pump 94 fuel

should i run a regular plug or can i run a race plug with so much street driving? and what part number ?

I agree have had the best luck with NGK's will never go back to anything else in my cars or planes.... And will stay as far away as possiable from champions (junk out the box)
I wouldn't call Champions "JUNK", they work great in a "SLO-PAR"!
