is this a 904 or 727

SOOOO sorry guys i didnt specify what i am doing ...talk about lack of info .....the 727 is same length as the 4 speed in this application bcoz im working on a B-body

i know 904 and 833 are same length on A-bodys ...but other way around for B-bodies.

i am actually surprised a big heavy car like this has a 904 .......you figure a loaded weight capacity with passengers and thats going to be quite a load ....it has an 8 3/4 but its only a 741 case.....odd

I parted out a 68 Roadrunner 4 speed car a couple years ago...383, 4 speed, and 741 open rear!!! The car also had XHD underpinnings and 11" brakes all around!! Go figure!! But you know Ma, anything was possible!! geof
