y'know, i think thats what it is. i looked at it a few years ago and the pattern on the back of the tranny had the same bolt pattern that the sm465 had. it was only 1in longer then the 465, and it didnt have the bellhousing. but mickey told me that the bellhousing from any gm engine should fit it. the only thing is, itll have sat without fluid for ~5 years now and theres a hole in the aluminium shift tower. otherwise, its fine.That is prolly a 2WD Clark transmission. It may bolt up to the engine, but it will take some major work to hang a t-case off the back.
