Spark Plugs
Does anyone have information on how to determine the best spark plug for a modified engine? I've removed all of the cross-fire and installed a hotter cam, aluminum 2.02 head, air gap manifold and a Holley 650.
I was told by the manufacturer of the heads to run an autolite 3933, but another source says 3924.
Anyone have any thoughts on this???
