Someone has posted a complete troubleshooting flow chart around here somewhere. Don't just throw parts at it without actually diagnosing the problem. #1 problem I have seen with the HEI is the rotor has burned through. This doesn't cause an intermittent stalling scenario, your truck will just run badly. #2 is the module. That troubleshooting flow chart shows how to check that. In all my time, I've seen only one pickup fail.
