I don't think there is anything interchangable betwee these two. It's possible the crank and rods are, and the transmission bolt pattern is identical. But everything above the block is different, as are the pistons and liners. If you need, there is a friend of mine who has some 4-107 parts for sale. All the top end stuff is good, and from a low time engine. Block and crank are trashed. She is zeehag, and I think posts up on here sometimes, but is a regular on Sea Knots, and Latts and Atts. Is also possible she has a manual.
