Anyone ever slap in a 4.7 ho into a Cherokee from a GC ?

Ive been thinking about this and wonder if any of you have done it.

 

I think the 4.0 has plenty of power if tooken care of.

 

I’ve never tried it, but I’m all for praying to the gods of horsepower. Just depends on the product, is it going to be reliable. That’s why I love the 4.0; I wouldn’t be worried about driving my war pony across the US and back.

 

Major undertaking!! ECU, wiring harness, and countless other things that I'm unaware of!! It would be a BIG deal, good luck!!

 

I reckon it would be a hard job. But man its gotta get better mpg out of a Cherokee than the GC. And all the HP its got. Would be fun to smoke a Mustang or two.

 

Just go the distance and shove a hemi in there.

 

xtreme 4X4 did a TJ with a Hemi so someone had the wiring harness which would be the big obsticle IMO. The frame/unibody will need some serious reinforcement for a V8 of any kind but it has held up to SBCs and a few BBCs so it can be done. Go for the Hemi and you will be in some serious HP then. and still into all Mopar.

 

I like the idea Blue. Just imagine taking the cherokee in for routine maintenance (just for the hell of it even if you do everything yourself) and the jeep technician says "oh, another cherokee..." and then he pops open the hood...........

 

Are you lifted and/or on bigger tires?

 

Yea, but Xtreme Credit Card Balance had someone make them a custom harness for it. I can't remember the name of the company off-hand, but they specialize in that kind of stuff.

 

easiest way to get the most power out of that thing is stroker. i'm building one. 4.2 crank and rods, in the 4.0. matches right up real well, minimal modification. ball park of 250 hp and 330 lb/ft torque. these numbers beat most chevy 350 in normal form.

it really isn't outrageously expensive to do, and retain all the stock components such as sensors, and ecu and wiring. and will pass emissions inspections

that harness they built for that tj w/ hemi was outrageous. they didn't say the price but it was hand built for that application, can't imagine what that cost. and it came with a new ecu programmed for a tj and that motor, so emissions tests that read info from ecu will not flag it. changing any motor that didn't come in a vehicle is gonna cost some bucks, and require modification. unless we're talkin about the 60's

 

I was trying to see on their website and I think it was "Painless Wiring" who built it. I agree that they have mucho bucks and don't spend it like we poor smucks would but that aside "Painless" is pretty reasonable about their pricing.

 

Yep a 4.2 stroker is a fairly easy mod..I almost wished I had had the motor shop do that to my motor but didn't want to pay the extra at the time..oh well new motor has plenty of power and loads more then the old one..if I had 4.10's I could lite up them tires..

 

why not a supercharger or turbo? they are putting them on everthing else.

 

uselss in an offroad vehicle IMHO...
