95 yj 350 swap

i am planing a 350 chevy swap in my jeep i have been told that a mid to late 90s chevy s10 4x4 trans will work for the swap anyone know if this is true and one more ? do you guys think i could get away with running the stock axial for a little bit like till summer i don't plan on wheeling it or beating it and what kind of donor vehicles can i get axials out of that will be the easiest one to put in it

Since your username is an RC car, maybe that is why you are referring to axles as axials. Now that I am done busting your balls, on to your questions. The transmission in lates 90's S10's would also be found in full size trucks, I think maybe what you heard was to use the transfer case...maybe. I believe the S10 used an NP231C which is very similar to the NP231J in your Jeep. As far as your axle surviving...I have heard of guys running a D35 behind a V8 and having it survive, but you will need to be very careful. I have also heard of D35's breaking behind stock drive trains. A Ford 8.8 is a very common swap. Do a little research on it, there are plenty of posts on it in this forum.

With my 350 swap i used a 700r4(chevy 1/2 ton) adapted to the stock transfercase with a AA adapter. As far as the stock axles they will work on the street but not so well on the trail. I broke 3 rear axle shafts and one front axle shaft within the first year.I upgraded my front axle to a HP dana 44 from a 79 3/4 ton ford. The rear I upgraded to a 14 bolt from a 79 3/4 chevy. As far as any swap I would buy all of your parts first and make sure you have enough funds to finish. Because the little parts add up fast.

I swapped a Chevy 406 in mine with about 400hp. I am running stock axles. Using a 700r4 transmission from a 90s blazer. The transmission lost 3rd gear and overdrive in the first 20 minutes of testing it out. I decided to run with just 1st and 2nd gear up some sand hills in my area. The axles held up just fine, and trust me, i was not being easy on them, and they still havnt failed me yet. I would recommend putting a bit of money into the transmission before axles. I plan on getting my trans rebuilt with a manual valve body and slap shifter this spring to keep my rpm's when I need.

Also went with a slip yoke eliminator kit for the transfer case and a custom driveshaft from Tom Woods Driveshafts

I have had better luck with 350 and 400 turbos holding up than any of the overdrive autos
