I do not know the exact differences but I think the HO PC units had a stronger sprag, might have had an extra clutch pack, probably had a different governor setting and different valve body shift points.
Std rear end for a 428 HO a/t B body was the 3.42:1. For some reason they listed a 3.23 for m/t cars but since they didn't make any I am not sure how accurate that is although it is probably applicable to GP's.
