ok a friend of mine has a 94 s-10 two wheel drive with a 4-cylinder 5-speed, all stock. we are looking for a wrecked s-10 or blazer with a 4.3 to swap in but he wants to leave the five speed in it. my question is will the 4.3 bolt up to the stock 4 cylinder tranny or will it need a different bellhousing? thanks for any input.
