Last weekend I was racing my 69 GTS 340. The engine has about 1000 miles on it. After I beat as 66 Charger with a 440. I was coming back and I believe I over revved the engine. It backfired and died. It would not restart. Checked and I was getting fuel. Then popped dizzy cap off. Rotor turned. Discovered the points were welded together. Popped them loose. One of the contacts fell off so reset the gap to get it to run. Limped it home (50 miles away) It didn't seem to be running on all 8. Got it home. I changed the plugs, dizzy cap & rotor. Put a Pertronix electronic conversion in. Changed the coil. Did a compression check. Around 150 PSI/cylinder. I felt the exhaust manifolds. Number 1, 2, 8 and possibly number 4 are cold. I even changed the distributor out today. No difference. The timing chain is basically new (1000 miles on it) I have the Mopar Performance tensioner on it. I even pulled the rocker covers off. All the rocker are articulating as they should. I also checked the spark plug wires. I am getting spark on the dead cylinders. Any Ideas?
