The trans was removed from a 90's 2wd 1500 chevy truck. My dad said that the previous owner said it was rebuilt. Dad bought it and we never ended up putting it in anything. I think he paid $200 for it. I can't verify any of its history and can't promise that it works, so I'm selling it for $75. If you take a chance you could get lucky here.
The block is a ~1969 vintage, 010 casting, 4 bolt main, 350. There might be a cast crank to go with it too (can't remember). It needs to be rebuilt, but it is a very good foundation to build a performance motor off of. $50
