Re: Thinking of going from MSD to HEi

Large HEI, BEST ADVICE, GET THAT DISASTER OF A COIL OUT OF THE CAP and that included all the "performance" in cap coils as well. THE single most frequent issue with large HEI is not IF, but, WHEN the epoxy coil begins to fail, taking module after module to fail "for no apparent reason".

Noting fails "for no reason".

Nice oil filled coil, such as NAPA IC12 (NOT AN IC12SB), or, O'Reilly's 2-5195 will work wonders in saving modules and coil failures on the large HEI's, and they will make a touch more spark energy because they don't run nuclear hot.
