SOHC to OHV swap

SOHC to OHV swap
What will I need to swap my whole ohv 4.0L with a ohc 4.0L. It comes with a harness, computer and every accessory so that's not a problem. I'm wondering about the frame and motor mounts, throttle cable and main harness that plugs into the engine wiring harness. It cam out of a manual and I have a manual also so I think the new computer should be fine right?

I think you'd be better off with the motor mounts and such because of the 4.0 OHV engine. The guy I know that swapped a 4.0 SOHC into his 97 4cyl ended up getting another frame from a V6 ranger with 4wd so he could also set up the suspension properly. He never liked the way his motor sat with the 4cyl motor mount locations. I think you ought to be alright.

emissions components,

A/C activation,
PATS,
etc., etc.

The fuel pump should be the same and the regulator comes with the engine.
the only emision problems that could posible give me a problem may be the evap system or the 02's.
A/C activation should be the same.
I really hope the PATS system doesnt give me a problem, where is the sensor for that and does it have a seperate module in or does that run off the ECM?

Also: the speed sensor method and wiring is a completely different system for 95~97, 98~2000, 2001-on.
It would be good to have a Wiring Manual/EVTM for the year of the donor engine and one for your truck.
Here are some threads to look at.

I had one when I ran a dual staged setup a while back.
