If the 4L60 will fit a small block Chevy V8 it will be a bolt-on to the 2nd generation I-6 engines (194/230/250/292) Not sure about the ones behind the 231/4.3L V6. It would also fit the little 4 cylinder used in the early Chevy II, the Post Office Jeeps and Mercruiser stern drives, but I doubt if the 4 cylinder would have the torque to pull an OD trans.
