Re: 69 El Camino distributor upgrade
I'd avoid the MSD Blaster coils all the way, proven they are still problem prone.
ALWAYS test a coil off the vehicle, find an auto parts store with an off vehicle electrical tester, let the coil run on the machine, let it get all the way to operating temperature, ONLY way to get an accurate evaluation of an ignition coil.
Resistance value testing is no longer accurate, nor workable, unless the coil is all the way dead and done in.
I agree, maybe you can suggest an alternate coil that will live and fit his needs.
