I purchased a 69 Mach1 with a 351 W motor from that year 1969. This car was converted from an FMX auto to a stick.
The car has a large cast iron bellhousing 164 tooth flywheel I assume.
My problem is a pretty good engine vibration, runs well but vibrates! Were there two 164 tooth flywheels made to fit this engine? I am told it should have a 28oz imbalance flywheel. Is there a flywheel with zero balance with 164 tooth also?
I am "hoping" that the car has the wrong flywheel. I already changed the damper trying to solve my problem.
any help would be greatly appreciated. I am an auto tech with 40 years experience, so please understand my frustration
