Re: Spark Pllugs for Chevy 350
I'm calling BS on the splitfires, always did, always will. Spark only jumps to ground, and the easiest one at that............. SplitFire" plugs caused an extra heavy spark <br />If your mechanic believes that a spark plug is making "extra heavy spark".....and you are here asking for a second opinion, well, you are getting one. The coil and Ignition system make ALL the juice, never the plug. 42 years of 350's and Harley's tell me that this guy raced these motors hot and on the edge of detonation, and those marks are melted aluminum from that, not the plug........run the 43's, everyone else does. And check the timing......
