I'd be willing to bet, since the new module didn't fix the problem, your old rotor has a hole burned in it in the center under the end of the contact.. Or the contact button in the cap has burned away.. I've put basically stock HEI distributors in race engines that have 12:1 compression and turn 7,000 plus RPM and never had a failure. The 454 in my '71 C/10 has an HEI.. Never gives me any trouble.. The main problem with today's GM HEIs is most of the modules are Chinese crap...
