Identify 727 trans

A W-150would be 4wd.
The clutches and such would be the same but the tailshaft housing and output shaft wouldn't work, as it is much different than 2wd parts. So the front case and innards would work the back half would not.
But that wouldn't have anything to do with fitting in a /6 or a v8 case.
What would though is if you are working with '64/65 parts as those were different and won't swap into a 70s or newer case as up til 65 the 727 had 2 pumps.
I've known people to gut a /6 specific 727 trans and scrap the casing over the years, as everything but the front case will work on v8 models.
