Engine 304 to LS?
Way easier, but I love the fuel injection, tuneability, reliability, and parts availability of the GM small block or LS. Had the 304 in two prior CJs and was always dickering with 'em.well may just have the 304 rebuilt put an edlebrock intake and 4bbl on it. sounds way easier
All of that is true. However, if ya' experience motor failure you can get parts from darn near anywhere and not wait or search. Piece of mind has its value also.I haven’t done the swap but you will be out for a new radiator, hoses wiring, power steering hoses, motor mounts, trans adapter/ flywheel, exhaust, fuel pump and lines
Also if you keep the LS as an EFI you need ignition and computer as well as hi pressure fuel system

Now I’m a purist at heart and want to keep it all AMC. I’m not a GM fan but I understand why someone would want a LS motor in a Jeep. I bought a 304 years ago and put it in my 86 CJ7 and It felt way better than the in-line 6. The 304 in the CJ7 felt like it was a better set up. I sent the engine out and had it bored out .030 over and added a cam and a Holley carb on it, and felt that it had enough power for me. I’m not mud bogging, this was my daily driver, and occasionally off road use.So i recently bought a 79 CJ7 with a 304. The 304 is shelled. My question is should I swap it out with an old LS moter I have or have another 304 rebuilt? Has anyone done this and can give me a price comparison between rebuilding or swapping to LS?
