Definitely different and haven't found anything with it being done in a cj. Was just going to do the LS 5.3 but really don't need the v8 and you have the same wiring harness brake down so figured why not. They put out 275- 290 HP depending on which one you get so that should be plenty good.

Right now the only problem I see is the exhaust dropping on the same side as the t-case but worse case is bring it over the frame rail like the v8 headers do.

Finding the right flywheel and clutch parts to mate to the sm465 might be an issue as well.

Well I pulled the i6 from the trailblazer. It's a lot bigger than I thought it would be and definitely longer. Might be a reason why I haven't seen any write ups on it in a CJ.

Tape measure is your friend. One thing I really like about the 258 is that everything is easy to reach, which is just one reason I never considered a V8.

EVERYTHING's easy for the guy who doesn't have to do it.

The width will be fine. It's the same length as the 258 when you include the fan on the 258. Trailblazer had electric fans so I guess that's where I'm going with it. I have seen a couple pics so I know it can be done. I will just figure it out as I go. Have to order a new bearing retainer for sm465 because the one I have has been machined for stock bell housing and Jeep clutch.

Just an update, haven't even got started on the swap. Finally got around to building a motor for the 66 mustang and should be done in a week or so. Also doing a 6.0 LS swap in my son's 69 GMC short bed and about half way through it. But that's where I'm at.....
