By using my dual point distributor, I can still run a tach drive tachometer & leave the factory wiring intact, just disconnect it & if the MSD unit goes out I can hook it back stock & get it back home on the points & not be stranded.

Either way, it’s still much more difficult to set up a curve without being on the dyno. The programmable stuff is great. But you still need to know what key strokes to make.

Just because you think it won't make it true. Horsepower is KING. To dispute this is stupid. C. Alston
