Definitley looks likes a buick or pontiac tranny. You can tell by the dip on the top of the bellhousing as compared to the point on a chevrolet tranny. As to what model can"t tell without a pic of the pan.

yup on the bop.

its a car tranny because on the long tail housing. a truck tail would only be about 4-6".

it can be a th400 or a th375, a th400 with a 27spl out put shaft, not the 32spl.

i have the chevy version [chevy bolt pattern th400] sitting in the garage looking for a home.
