Transmission blew in Automatic 65 Barracuda

I think you may need to offer a little more info. If it has a later trans to match the motor, that is going to make a big difference as to what I would do! Does it still have the original trans? Did they change the converter when they swapped the motor? The register is smaller on the front of a 273 converter and will waller around in that later crank and burn things up! Does it have the original cable shifter?

More info please!!.....
