What would you recommend the correct plug gap be on a 351C 2v with performer intake and 4 bbl carb pertronix ignitor ignition and flame thrower coil....I was thinking .040 would make it ..Thanks in advance.....Lance

.045 is what I run on all my cats w/ this setup. I believe Vic Yarberry ( Cougars Unlimited) deserves the credit for this information. Good luck!
