|We've been using these distributors for a few years now. We've used them in all applications and we have yet to see them skip a beat. This has to be the most reliable and cost effective ignition system out there, it features a high quality brass terminal cap and rotor, high output in cap coil and module, adjustable vac advance unit. We check and set the gear end play inhouse as we've found many to be a bit on the loose side. Just plug 12 volts into it and go!!
