Engine '69 Dauntless V-6 swap for a '86 4.2??

[Joe28]

Here is my problem,( today).
HAD a '89 YJ, with tired AMC 258 i6 / 4.2l . I bought a ," rebuild able " 86 AMC 258 i6 / 4.2l to redo and drop in it.
Got a WILD offer to sell the YJ ( everything I own is for sale.... At the right price)! Couldn't refuse, so now it's gone.
New owner didn't want rebuilt AMC 258 i6 / 4.2l on engine stand??!!
So, now the fresh motor sits in corner of shop crying!
I found '69 CJ5 , looks great, but, has Dauntless Buick 225 V6 V-6 motor in it, ( I assuming original drive line).
1). Do they make an adapter to convert this to a AMC 258 i6 / 4.2l ?
2) who makes something like this??
I understand that motor mounts, linkages, radiator, exhaust etc. will have to be fabricated.
I've done a few Jeep swaps before, Pinto engine in a Willys 2B, Chevy 283 in a 70's CJ, Ford 302 in a Willys Wagon, so, I'm not totally in the dark here.
Thoughts? Ideas? Any info?
Tanks!!

The 69 CJ has a short nose. Check to see if you can fit the inline six AMC 258 i6 / 4.2l .

Check with Novak for the adaptation.

seriously though, short nose, I'd use a Buick 3800 V6, check with Novak

If you're going that far might as well use one of the super charged Buick 3800s

You don't really gain anything with that swap but a major fitment problem. There was a good reason AMC extended the fenders and hood in 1972 to accommodate those longer straight 6's.

But back to the original issue. The 225 V6, in my opinion, was the best stock engine ever installed in ANY CJ. Light, compact, and an abundance of low end torque. It also responds very well to an aluminum 4 barrel intake/carb, and headers, with or without a cam change. If the current 225 needs a rebuild, pretty much all of the later 231's will bolt in, odd fire or even fire. A Buick 350 will also sort of bolt in-another excellent Jeep engine. Also relatively light and possesses a long stroke with excellent bottom end torque.
