I have a 71 CJ5, it has the shorter front end. I would like to swap in a 4.3 liter V6. I haven’t really done much with truck engines before, so this feels a bit overwhelming to me and I hoping for some guidance. From what I have read the common swap includes pulling the entire engine, ECU, and wiring harness from a donor vehicle and swapping it in. I don’t think I want to go quite that route though. I would like to get an engine that would normally use a carb and use something like a Holley EFI, thus eliminating the need for the factory ECU and all the wiring/programming issues that come with it. First, I am trying to determine what year/version engine would allow this as most already have fuel injection and I don’t think they would accept a carb/EFI. Do I need to get a crate engine if I don’t want something extremely old and high milage? I think one thing I would need is a distributor, I found this one: A-Team Performance 4.3L 262 V6 EFI to CARB SWAP 65K Coil Complete HEI Distributor, Spark Plug Wires, and Pigtail Harness For Chevrolet CHEVY/GM GMC 90° V-6 One Wire Installation I am hoping to mate this to a SM465 transmission and use my existing transfer case, a dana 18 with a single stick. I have read through the Novak guide on this and it seems like a good combo. I’ve included some pictures of the tub I have been working on cutting out all the rust. It probably won’t be too pretty, but I wanted to see if I could do it anyway. Thanks!
