I have a 64 Belvedere in the shop right now. Customer reported a miss under acceleration.
I did check the ignition and fuel, no obvious problems. Under accelaration it pops out of the exhaust and I can hear a slight knocking noise which I would locate somewhere in the rear of the engine, but not from the rockers. The noise dissapears when the engine is above 1500rpm.
Could a wiped cam cause the missfire? Edit: collapsed lifter would cause the same symptoms, correct?
Thanks,
Frank
