65 cuda 273 to 360 tranny hookup

The 65 trans may have a different spline count than 68 and later. You can switch the front drum (65 will be 4 disk, mid 70's may have 5) and reaction shaft support to the later setup and use the later style converter (I think the pumps were the same). Same goes for the mainshaft and tail housing if you want to get rid of the ball/trunion. Ball/trunion parts are more expensive and harder to find.

You will have to use the 65 valve body with the cable shift case. OR use a later complete transmission and a shifter adapter cable from www.imperialservices.net
