What is this going into, A front driver car, or a S-10? I belive the S-10 Blocks can be ID because they have the holes on the side for the side type motor mounts, but the front driver engines are mounted on the front and rear of the engine, with no bolt holes on the sides of the block. (I think!!)

This should be a very easy engine to find, try car-part.com
