Truck 727 for my Dart.

Wow didnt know about the 30hp difference! I always thought the performance gain was just less weight. My 904 was behind a 76 Scamp 318 it is complete w/ converter and linkage. Sounds like it would be a lot of work to go with the 727 just for a mild 360. Would the 318 converter stall higher behind the new 360? Thanks for the help Fishy.
