Guy bought a '69 343 motor, is putting it in a Jeep. Wants to know if he'll have a problem with an auto trans flexplate interchange, for balancing. I thought they were mostly harmonic balancer issues, but then again, maybe the 4-speed flywheel has some balance to contribute. Just wanted to be sure to pass that info on to him correctly. So, how do you balance a '69 AMX 343 motor?
