What spark plugs?
I'm thinking of getting a new set of spark plugs for my TPI motor. Did any one use the SplitFire3 Triple Platinum Spark Plugs on his TPI motor?

Axle/Gears: 9" from 57 ranchero unsure gears.
I tried the +4's on mine had more probs after a while, initially they worked great I dont know if the MSD killed them or what, but they lasted maybe 3-4,000 so Im going back to the rapid fires I had see if they work like they did, I did notice while installing them that the tips of the electrode looks different than what it used to so I hope this dosent make any difference.
