Truck 727 for my Dart.

Hello, I'm putting a mild 360 in my 67 /6 Dart. Will the 767 TF that I have fit no problem? P3898866 5463 7274 I think its from a 76 small block truck. Also I appreciate the importance of a high quality converter in a high performance vehicle but this it a pretty luke warm 360. Any off the shelf converter recommendations would be appreciated. Engine is low comp, Comp XE268H-10 (.477 .488 @.050 224 230), performer intake and 650 carb. Going to be a cruiser. Thanks for any help.
