383 Harmonic balancer question
Automatic or 4 spd ??
Cut your oil filter open, poke a hole in it with a scratch awl and open that hole up to 1/2" with a punch, then zip around the can with an aviation snips. 1" down from the gasket seal end on the filter. See what's in there. If clean go on to looking at the torque converter.
Something that is shaking that bad has got to be a miss matched external balanced torque converter to an internal balanced enging. You have extra weights slinging around there that should not be there.
Also you may have an External balanced 360 Flywheel bolted on your internal balanced 383, they will bolt to the cranks, 318, 360, 383, flywheels all bolt up to the same crankshafts.
Is this a new engine swap into an old drive line of a different car that just came up on this build. Or is it an existing drive line where the vibration just started out of nowhere ???
360 external balance flywheel:
360 External Balance Flex Plate:
Take the weights off for internal balanced engines:
For external balanced engines going to internal balance flywheels:
Lots of combinations to get it wrong, need to make sure you have the right combination to get it right.
