4.2 vortec in yj

i have a 4200 vorthec chevy inline 6 , it has 291 hp and 290 foot pounds. how hard would it be to put that in my 88 yj , as far as wiring and sensors and computers. do you know if it can be done , or is it even worth it when i can put a 4.7 stroker in a little less power but a drop deal . any input would be helpfull thanks

'89 YJ, 4.2L, ax-15, B&M shifter, 1" BL, TJ flares, '99 intake, '91 EFI, 5.0L explorer injectors, GenRight tank & stretch, 35" ProComp Xtreme muds, 52" chevy springs rear, 44044 Ranchos front.....

depends on the length of the chevy motor and what you might need for adapters to make it work as well.

The motor is a lot smaller than the 4.0 in the Jeep. It's an easy swap (there are lots of adapters and junkyard parts that fit), you'll get better gas mileage, and it's a good engine. Best V6 you could possibly put in your Jeep.

Don't forget though, it's a cut-down version of the 350. There are a lot of bolt-on aftermarket performance parts for it (it's cheaper to fix), and you can get another 100+hp out of it without spending a ton of money.

100 Characters is not enough to have an interesting/relevant signature.

I think hes talking about a 4.2 inline six from a trailblazer...

Oh right, I always get that mixed up with the 4.3.

Yeah do the 4.2.... it's a sweet engine.

Any time I've seen this motor discussed it seems there isn't much in the way of support for it and a 5.3 or even 4.8 v8 is a better option. Maybe if you happen to have one complete and running it would be worthwhile, but I wouldn't recommend going out and buying one for a swap.
