65 Valiant swap 273 to a 360

And, 2nd issue, since I didn't read the thread all the way through, is that your 273 torque convertor WILL work with the 360. Agreed, the 273 is neutral balance and the 360 is not, all you need to do is buy a 360 spec balance torque convertor plate from Summit, or anywhere else.
