If the current 383 converter never comes out of the transmission, it seems the snout shaft diameter will be the only issue. What about weights welded on the torque converter? I havent removed the 383 yet so I dont know what it looks like yet.

Im concerned about balancing issues. Thanks DJ I would be concerned too since the cranks are different weights. I'd be looking for a converter from a steel crank 440.

Canada	The convertors will work (both applications are neutral balance). the 66 has different transmission splines than the 72 transmission so you will have to keep the 66 convertor with the 66 transmission or the 72 convertor with the 72 transmission (which I think you know). Also the flexplate convertor bolt pattern could be different so check that. Sheldon
