Sounds like it should be a good converter.
'67-'81 Chrysler Torqueflite 727 Transmissions (24-Spline)*
The first step into serious high performance, the Breakaway® is a great torque converter for moderately modified street machines and weekend racers that are also used as daily drivers. It provides approximately 2400 to 2600 RPM flash stall without negatively affecting part throttle driving. Designed for both efficiency at highway cruising speeds and to launch hard at wide open throttle, the Breakaway® is a fantastic all-around torque converter featuring furnace-brazed fins, needle bearings, a hardened, pre-ground pump hub and computer balancing.
