First off, I have a head injury and can forget some major stuff and have difficulty communicating. I also have to do this multiple times to get it right. However, I have owned the car since 1980 and know it very well.
The engine has a bad misfire and overheats. I have eliminated all of the typical causes under the hood.
It is currently running on a factory ignition box, new Mopar distributor with a lock plate set at 34 degrees and an MSD Blaster II coil. The engine is a factory .040 over low compression engine with a Hughes Whiplash cam, a custom Dynamic Converter that stalls at about 3,000 RPM. It has a new 26” brass/copper radiator, motorhome water pump, 906 stock reconditioned heads, short tube headers and a Mopar dual plane manifold with a QuikFuel 780 w/vacuum secondaries and 5.0 power valve.
I believe the problem to be in the electrical from the bulkhead connector back. I replaced the ignition switch wiring harness last winter, the starter relay and reverse lockout switch have also been tested and replaced.
I have intermittent trouble starting the car with the key. I recently re-connected the seatbelt switches. I believe that all of the trouble comes down to something in the electrical system from the firewall bulkhead back.
I have tried multiple distributors, ignition systems, MSD Streetfire, points, plugs and wires, currently running the FireCore wires. I have checked the cam centerline.
I am at a loss. No matter what I do I cannot get the car to run right.
