Default Engine choice for swap, especially for weird ones...

I've been doing a lot of reading. I'm doing the suspension and stuff first, but will eventually get around to adding some power to my 2000 sport. This isn't really a thread about my truck though, so it just goes into Chat.

What goes into picking an engine to swap in?

Why does nobody seem to swap in either 4.7 or 5.7 chrysler V8s? Is it really that much harder than the SBC?

When considering an absolutely weird swap, what kinds of things should you look for? I mean seriously, at 3200ish pounds, the Cherokee isn't much heavier (if at all) than a LOT of cars powered by these newer turbo 2.0 4-cyl engines...

Funny you should mention this.
When the little 2.5 I4 dies in my rig, I will hopefully be ready to do a 4.7 swap.
Of course you will wanna have some frame strengthing in place by then. The other thing is to do a complete deivetrain swap (transmission, transfercase).
I have the crappy little AX5, and the thought of having a modern automatic tranny is kinda nice.

The thing that is taking some time here is to source ALL the wiring for the swap.
Do you plan on using your factory gauges?
If so, how will you make the modern computer talk to them?
Personally I will more than likely use aftermarket gauges, or adapt something out of the vehicle I source the DT from.

Suspension is also the easy part.
I am sticking to the OME set up I have now with a few modifications.

Swapping in the 4.7 or 5.7 is the easy part.
getting it to run, and all your stuff working is the hard part.

I always wondered why not a 4.2,4.7 or 5.9 myself. I’m sure it’s been done just not as common. As for any other newer or weird swaps I think it would take so much fabrication that not just anyone would be doing it. It would cost more etc. We have a VW Touareg with the 3.1 vr6. It’s 100hp+ over a 4.0. With the 6 speed auto and 4motion awd. A Cherokee would haul with that setup. I can hardly even get the wheels to spin in snow with cheap all season tires. I realized this winter just how not good a stock Cherokee is in snow compared to the newer computer controlled awd systems.

Just realized I wrote 3.1. It’s a 3.6. Also weighs 5,000 lbs plus. Gas mileage though! It’s similar, maybe worse than an XJ. Lol. The V8 version is not much worse. 1 or two mpg less but it’s a 4.2 350 horse.bith the V6 and V8 redline at around 6800rpm. There’s also diff locks and a low range selection. Also there’s a V10 TDI version. Lol.

All that hat would be meaningless though. I want my Cherokee to stay Cherokee so the most I would do is maybe a Chrysler V8 swap. If I want a vehicle with a VW engine and drivetrain I’ll buy a VW.
