I just put the carb intake and distributor on my 4.0. Had to use the 4.0 exhaust. My old BBD runs it just fine, giving great gas mileage so basically any carb that can handle the 258, 4.2 can do the 4.0. I also stayed V-belt by swapping the front parts over. My pilot bushing needed a little rework, OD was a big big, but I hear you can buy the correct size. Had a muffler shop join the 4.0 header to the CJ pipe.
