I have a 350 30 over stock rods and crank, 76 cc heads shaved to 70cc, 504 lift cam, accel coil, msd module,good wires, timming locked in at 36. I have been running ac43ts plugs. Have not really had a problem, however its about time for more and I have heard alot of people using Autolite plugs. What autolite should I run? I dont really know how to read plugs so I assume what I have is ok but always thinking how to get better. Turning around 6500 rpm

I wont get into all the reasons why and my reasoning, but I have raced mx and micros for the last 20 years basically. In that time I always used NGK plugs, and for the most part had minimal problems that wasn't induced by an outside force.
Now in a 360 sprint, Brodix lists B9ES as the recommended plug, and thats what I ran all last year and part of this year. I decided to try out a set of AR 3933 plugs recently, Couldn't do what the NGK's have, I have since went back to standard B9's and no problems... I don't believe its coincidence either. You all can run whatever you want I'll stick to NGK's from now on, thats just my opinion..

I run bout the same engine combo and i use R44T,a little hotter but i can't afford to foul a plug at idle,if the ac's are fine now i'd keep using them.
