Xj motor time.

[Jester32]

Well my 4.0l has finally went on my xj. Now should i just throw in a 4.0l or should i swap in a small block. Only thing im worried about is the rad to keep a small block cool is like 600 bucks and the kit to adapt the 231 to the th350 is 700. Now i could go with a mercedes diesel i 5 or something two.

Do you have the smog equipment on the small block to match 92 requirements? I'm a californian so thats a big deal here. Is the motor complete with headers and all? I would say you could run the sbc on stock axles but the lead foot will kill them. A poor mans stroker kit could prove to be cheaper in the long run, and still give you that needed HP.

Im in alberta so no smog. I have complete chevy drive trains. I got a dana44 rear. Up here machine shops suck. Looking at about 4500 to rebuild a 4 l. So. Im trying to stay away from them.

I say stroke the 4.0 some kits push like 320 hp an almost 400 torque

I guess you just need an extra large shoe horn and drive shafts. If you modify the radiator core support you can fit a much larger radiator ie junk yard salvage. the electric fan can be bought at auto parts store for under $100. Hows your t-case, np-241 with the donor trans?

 

[Jester32]

It is a left hand drop. But not sure if it is clocked right i may go for a adapter to use a 231

i have the sbc (383 stroker) in my jeep with a th350 and i used a adaptor from advanced adaptors and ran my stock dana 300 transfer case best thing i ever did man this thing has so much power and it responds very nice its like a new machine good luck with yours u will love it with the sbc in it

 

[Jester32]

Im pretty pumped i drag race in the summer time. I have a ton of sbc parts.

 

[Jester32]

I even have a holley projection kit thats waiting for a home.

 

[Jester32]

Just wish i had a garage. Its gunna suck doing it in -25 lol

 

[83-cj-7=383-stroker]

[XjShake]

Well jester sux to hear bout your luck but whatever you do let us know... mines probably do the same mines probably gonna die soon

 

[Jester32]

It was bound to happen. I mean nitrous. 480,000 kms and a heavy foot im going with a tbi 350 and th 350 trans. Adapted to my np 231. Im putting a mild cam and having the heads done. A little better compression to with different pistons. All balanced etc. Built to keep the torque down low. And a nice flat curve. Im using a holley projection kit for easy of install. And it works great.

 

[Jester32]

Well it will work great. The projection was on my old chevy with 40" boggers.

 

[Jester32]

Well just got my motor back from machine shop. Pulled 338 hp and 429.8 ft lbs torque. Should pull alright. All below 5000 rpm just where i like it. Torque came on strong right around 1750 rpms.

 

[Jester32]

Just waiting for novak to get back to me on my mounts and adapters.

 

[hillbillys4x4jeeps]

I would bore and stroke the 4.0 with a nice RV cam.I would not put a small block in plus the 4.0 will get better MPG.

 

[Jester32]

I built this whole engine for the price of a stroker kit. Besides nothin better than a v8. Now it wont sound like a rice rocket. Im done with 4.0l. Had nothin but let downs. And besides my trans is probably cooked to and the aw4 is not cheap to rebuild.

 

[Jester32]

My 4.0l was horrible on gas. My big block chevy truck with 780 hp got the exact mileage my jeep did.
