Yes, it was out of a big motorhome, not one of the truck/van things with a camper in the bed. It was a direct fit and looks exactly like all of my A/B/E 727's. Same driveshaft was used too. Motorhome exhaust manifolds are center dump and will not work. Not sure about the C-body manifolds, but here is a link on how to use B-body manifolds in an A-body:
