    I have a 60 CJ5 with an F block that appears to be frozen. Looking at a 62 C10 with a 235 inline six and wanting to know if it will fit and what are the needs to make it fit and work.

    Even worse to fit than a V8, major radiator & firewall surgery required. It has been done way back in the day, also with Stude 6's, but never caught on for good reason.

    I've seen an I6 from a ford falcon in a cj but that allows for the 3/4" plate adapter. I think the killer will be transmission and lack of drive shaft length.

    In the late Kaiser years, Kaiser Jeep of Australia built what they called Jeep Combat 6. They had Ford 170ci straight 6 motors, the same engine used in the early Mustangs.

    It was the Aussie answer to the Dauntless V6 being installed Stateside. Apparently, the chassis and tubs were imported from Kaiser's US plant, and assembled with the Ford engines in Brisbane.

    You can get some idea from these photos of how much the CJ firewalls had to be modified to accept the straight six motors.

    Not sure I would modify a firewall just to shoehorn an I6, as it's just too easy to install a V6 or V8 to mess with cutting a firewall. My firewall and transmission tunnel were hacked up pretty good for some reason by a previous owner, and it took me 10-15 hours of fab work to rebuild everything to make it look good again.

    Yep. Another case of "just because you have doesn't mean you should use it". IMO, completely silly to swap any I6 in an early CJ, flat fenders or otherwise. You will be whittling away the firewall and that rarely makes for a sanitary installation. A 4.3 or a 225 would be much better choices even if you have to buy one.

    The Ford 170 is really short for a six, and the those Australian Jeeps had the firewall modified for the long engine.

    The 235 was old in 1962 (heavy), and you may have a 230 instead. GM introduced the 230 in 1962. I have seen 230 in a flat fender, but the back of the valve cover ends up under the cowl.

    Agree with above, no reason to punish yourself fitting an inline 6 when there are plentiful and excellent V6s available today.

    The Postal Jeeps overcame the inline-6 length issues by simply extending the grill shell forward once they moved away from the GM 4 cyl of the first generation (DJ5a?).
    As suggested above, just because you have the inline-6 doesn't make it a smart choice to swap it in. Sure you can make it fit, but its much easier to just put a V6 or V8 in an early CJ5.

    You Sir, have more knowledge about Jeeps than anyone I’ve ever heard of. I don’t know how you possibly retain all this information. I can’t even keep track of the days of the week. And I’m 42.

    It helps to be indoctrinated at a young age. What you learn as a youth tends to stay with you. Working in the parts department of a Jeep dealership as a teenager was formative, and I hung out with friends from there. Then I worked auto parts counter part-time and summers during college. Plus I read a lot. I consider your reply a compliment - thanks.

    After reading yall's replies I will definitely look for a 4.3. I did put a wrench on the crank/harmnonie balancer nut and it did finally give. I did not have anything in a plug hole to see if the piston was free or if I did something to the crank. Could use some input here. This is a long term project that Im trying to fit in between othrer honey doos. I had soaked the cylinders with marvel mystery oil for several days prior to wrenching. Thanks for all of your input. I really appreciate it and it gives me a lot better idea of what im dealing with and the effort needed going forth.
