There isn't much info on the SOHC swap as the OHV is more of a direct swap.

This guy has a BII with a 4.0 SOHC

(He's in Utah, but I've never met him)

The 4.0 OHV is a much easier swap, and is done more often, which is why there is more documentation on it

The SOHC swap is tougher, as there is a lot more involved, swapping the entire engine bay and the dash would be the easiest way IMO

sounds to me like the 4.0 ohv would be the way to go then. any good documentation on that swap?

That was a neat swap the guy did putting in the 4.0 SOHC. Helluva lot of work, but when you get 200+ hp with out have to go to a 5.0 it might be worth it.
jims89broncoII: Your 89 is one of the easier swaps for a 4.0 OHV, most everything from a 91-95 X is plug and play. If you haven't already found this link, it is interesting and informative. Also pertains directly to your 89 B2: http://www.broncoii-ranger.com/forum/viewtopic.php?p=9135#9135
If you haven't already done so, I suggest you find an X with a good engine and swap everything you can or want. I started with an 86 B2 and a 92 X with an automatic/154e that I didn't want. The B2 now has the 4.0, basically the dash, (I got a dash and all the interior from a 89 & 90 B2, put the X harness in the 90 dash.) yours won't need that, D35 front axle, soon the 8.8 rear and springs, a M5OD-R1/BW1354m and the 31's and rims from the X.
When I picked up the X, I was amazed at how much wasn't changed from my 86 B2 to the 92 X, and after seeing all the parts that I have used from the X, the $450 was well worth the cost. If I had bought them separate from a wrecking yard it would have been close to $1500.
Good luck with your project, it is time consuming, but nearly a direct bolt in
except for the rear end.
