4 speed or 4 speed OD?
I had a regular 4 speed behind a hot 360 in a 73 Dart Sport...I changed to a OD 4 speed and loved it! Great street power between lights, and highway cruise RPM was noticable.
As for strength, work fine no issues! Drag out the 1 st gear and I would skip 2nd straight to 3rd...lol 2 speed with OD on the Highway! I would do it again...was 3:23 sure grip by the way
