I purchased a Mallory Unilite conversion module in 1985 after the dyno operator sent me down to the speed shop when my Mallory X points were crapping out after about 5,400 RPM. That same Unilite module is still puttering along just fine and my old Sun machine can't go high enough to find out the upper RPM limit.

I wonder if the proponents of points have ever checked them on a distributor machine? Most start taking a dump in the low 4,000 range with very few making it anywhere near 6,000 RPM. Fine for grandma to go to the grocery store back in the day, but the industry has made some progress since the horse and buggy days. We just ran an engine on the Westech dyno and the points distributor was starting to get wonky about 4,400. The interesting thing is the points looked pretty good up to about 5,400 on the machine but on the engine they started giving trouble way below that. Maybe running harmonics that wasn't there on the distributor machine upset the points? I brought along a cast iron distributor with a Fast XRi module and it kept things together for the rest of the day. The first photo is what I usually see when running points at moderately high RPM's on the Sun machine, and the second is with an electronic module installed. Give me Unilite, XRi, MSD, or anything but Pertronix (I wonder if 95% of the bad press about electronic modules doesn't originate from Pertronix failures).
