360 Swap for the 65 Dart

it's in, it's running, no miles on it yet as we've been having vibration problems.

Swapped converter and flex plate, had a 360 converter made for the early transmission and put in a new stock flex plate.

I'd guess I lost about 1/2 of the vibration, still have too much and I think it's in the engine.
Under acceleration the vibration is there, let off the gas, vibration is gone.
Engine idling in the garage seems ok, rev it up some and you feel a little vib. in your seat.

I hate to think that the engine needs to come back out......


thoughts?
