Hemi swap question

Hello Guys,

I'm not as experience as majority of you here, however i want to plan further build up on my jeep that i will try to accomplish within a year or two (depending on how much funds i'll have).

First of all i own 1992 wrangler with 4.0L (6 cyl.) with 180k mileage. I do not plan to ever go above 33 inch tires, so far i'm solid on 31s as they are widely available (cheaper as well) and do the job just right. The upcoming change this spring is suspension, i want the 2 inch rough country lift with 1 inch shackles and 1 inch body bushings/mounts. Also replacing the floor pans. After that i have no solid plans and i want to explore the option of swapping in a Hemi engine 5.7.

With that i have few questions:

What will i need to swap along with the engine to accommodate the power (will i need new transmission, drive train)? and is it necessary?
Which donor cars would i have least problems with to do the swap as well a pricing?
Lastly, does any one has a write up on the swap?

Those 2" RC springs are going to have a hard time with a V8 swap.

I would not run stock axles with that engine. Period. At a minimum, I'd go D60's if it were me.

i guessed it's not a valid option, rather save the money and rebuild 4.0 when the time comes mean while focusing on other mods.

Sure it's a valid option, if you have deep pockets! That would be a major swap, with lots of fabrication, electrical & parts sourcing.

I think you'll be happy with the 4.0. They're a good motor & there are plenty of mods out there to get more power out of them if you want.

That motor would pretty much require an entire drivetrain swap. Engine, trans, axles, etc. Lots of money and time.

If you're fine with staying at 31/33 inch tires, the 4.0 is plenty with the right gearing.
