73 360 Damper...bad vibrations ..help

[701234Duster]

I have a 74 Plymouth with a 73 360 Engine from a police car and a 727 from a 73 roadrunner, I have vibration problems and was hopeing someone could tell me the visual differance in a 318 and a 360 Damper because I am not 100% sure my engine has the correct one. I believe the crank is shot peened? and there are two weights on the torque convertor

The 360 damper has a half moon shape out of part of it.If you look at it flat on a bench,with the front of it up it will have a shape like a "C".The 318 damper is not like that.

You also need to check and see if oyu have a 360 torque converter. THey have weights on them and a 318 does not.

Early 360's had a raised counter weight and later 360's had a 1/4 moon sized grove machined out of the damper.
He did say there were weights on the TQ..
