The AW4 computer looks for a signal from the TPS you woudl have to bypass that and get adaptors to run the AW4.

I had an aw4 I wanted to swap into my 5sp, and add a 203-205 doubler behind it but then I found a 350 with a th400-203 behind it, comparing a th400 to an AW4 youll be wanting the 400. If you have a stock NP231 thats not gonna last long behind the V8.

Aw4s are great but if they were that great youd see guys with big block suburbans swapping their EL60s or th400 with Aw4s and you dont.

If you go with a v8 get a v8 tranny and t-case.

The radiator size restraints with the XJ steering box are your largest issues for putting a v8 in an XJ. I pull the box and when with a hydraulic orbital valve and fit a nice big 27inX19in aluminum dual 1in core radiator for only $169 form summit. I couldent spend $650 for a be-cool radiator that fits in the XJ stock location and is still smaller then recommended for a v8.

My dual exhaust will be going through my sleved frame rails and into the rear fenders.

Carberators suck for anything more then flat groud driving. you get them off camber and a stalling engine will give you horse power compared to a fuel injected 4.0

Whats carpet?

My tranny tunnel and floors are stainless steel, nuthing but suspension behind the front seats.



You can see the cat behind the Passenger seat belt the tube follows the rear fenders so I dosent interfear with the suspension thingies.

if your talkin about an AMC 360, then check out this thread, http://www.naxja.org/forum/showthread.php?t=53767&highlight=401+mj he bolted an 401 up to a AW4. now if you were talkin about a Mopar 360 then youll need another tranny.
