Distributorless ignition (I'm new around here)

[Bruce Plecan]

Electromotive sells all the bits to do that, and even  a.
ZR-1 are a parts source but rare.
Alternatives use two electromotive sensors and tone rings, inside the oem
dissy
Some reading at the 332 site.
MSD supposedly has a v-8 dissy for SEFI so it has a synch signal, if I
recall right.
