V8 swap

It's about time to start thinking about the V8 swap for my YJ. I'm leaning more towards a 5.0 instead of a 350. Is this a good choice? And if someone could give me a quick run down of the trannys that would mate to these engines without wallet draining adapters from AA I would appreciate it.

Regards,

JT

Re: V8 swap

There is really no way you can get around buying an adapter if you want to use any of your stock components. The only way to avoid it would be to swap in a complete drivetrain from another vehicle.
I just finished a 5.0 swap into my CJ. I really had no prefrence between chevy or ford. I just wanted a fuel injected V8 and the 5.0 turned out to be the best deal at the time.

Check out the tranny section here at ORC. There is a lot of info there.

Re: V8 swap

I already got rid of the engine, tranny, and xfer case, so I'm willing to start from scratch. Something strong that will hold up against the 5.0 power, but not cost me an arm and a leg...

Re: V8 swap

Will this jeep be driven on the highway? Do you need an over drive? If not then i'd say pull a t-18 out of an f150 and then keep the t-case that comes with it (i think it's a 208, not a bad case) or pull a jeep t-18 and get a ford bell housing from an f150 and then use a bronco d20 t-case (unless you want the drop on the other side then use a jeep t-case). ARe you planning on an axle swap? If not your stock d30/d35 arn't going to like the power alot.

Re: V8 swap

I was hoping to keep the axels, but I'm sure thats out of the question. I'm assuming a 44 rear and 30 front would be ok?? So a 5.0 would bolt up to a bell housing and tranny (T-18) from a F-150? And the transfer case would obviously fit. Where would the front and rear drive shafts come out? Rear would be centered? And front would be passanger or driver side??? Thanks for the info. Appreciate it

Re: V8 swap

Hey rock-hog,

Ideal set up would be yours exactly. How much did you end up spending on engine, tranny, xfer case, all engine wiring, and axel?? Thanks

Re: V8 swap

All told I've spent just under 5500.00.The axle w/Detroit installed was 2000.00,the nv4500 w/all adapters was 2000.00,the engine w/rebuild,new alt&starter and radiator was 1200.00 and the labor on things I couldn't do myself was around 300.00.The tc is still my nv231 just w/sye and shaft that came w/nv4500.If I was going to do anything different it would be finding a FI engine instead of the Q-Jet carbed one,of course I would have spent more on the engine&install I think but it would probably have been worth it.nb

Re: V8 swap

I'd say either an 8.8 or xj d44 rear and then throw shafts from a '95 or later xj up front so you get 1 piece shafts (no front axle disconect) and 297x u-joints (same size as a d44 front). I havn't done the swap but i'm pretty sure the engine would bolt to a t-18. If you used a jeep t-18 you would have to get a ford bell housing and maybe input shaft and if you wanted to keep your drivers side pumpkin you would have to get a bronco d20 t-case (jeep d20's have pass side out put and ford t-cases have drivers side out puts), or you could swap in a ford t-18 and the t-case that came with it. As for drive shaft lengths you could mount it so the t-case is in the same place it was in w/ the factory t-case and then move the motor and tranny mounts accordingly.
