Chevy 350 swap

89'XJ · 09-10-2006, 04:38 PM

Ok I got a idea for my 89 XJ. I want to give it some muscle with a chevy 350 but I do beleive that I have to swap out my tranny and transfer case along with it. And I want to put a ford 9" in the rear and a Dana 44 in the front with a driverside dif. My question is what manual transmission and transfer case could I use?

im not saying u shouldnt do it, but a friend of mine put one in his cj7 and cant stand it, if ur climbing at all or not level the thing stalls out so much

Is his Fuel injected or carborated?

from the description, I'm guessing carbureated, I don't know of any EFI engines that do that.

As for what kinds of components, the ford 9 and d44 sound good, the Atlas 2 is a sweet TC and I'm not able to speak about the tranny, I don't know too much about transmissions.

You CAN use anything you want, but what you should use are the best components that you can afford

its not fuel injected

89'XJ · 09-10-2006, 07:40 PM

Yeah I dont think I would have a budget for an Atlas, I heard that a for np208 works but I dont know if it would match up with a chevy tranny.

as far as I know, you can match any transfer case to any tranny, providing that you can get or make an adapter for the different spline counts

find a 231 out of an older model jeep anything, they are very reliable and your jeep probably already has one. nothing wrong with them.

from what I remember, the 302 is the largest Chevy motor that will go in the engine bay without MAJOR modification.

bandit88 · 09-10-2006, 08:26 PM

chevy hasnt made a 302 in years,plus any smallblock has the same block size

knatdog55 · 09-10-2006, 08:27 PM

although they should have kept the 302 instead of going to a 305, i've had 3 vehicles with the 305 and they are hurting for power big time!

89'XJ · 09-10-2006, 08:30 PM

Cool knowing that the Tcase should'nt be much of a problem. I know that a 350 is a tight fit, but I've seen it done before I know that it must be lifted more than 3" so I'm good there but I should probably pull some measurments from a engine to get a better idea for it. As far as a manual tranny what would be a good pick I would want a 3 or 4 speed but I have been having trouble getting good specs. on anything.

JJXJ · 09-10-2006, 08:30 PM

The blocks are almost the exacts same size between the 305 and the 350. You can stroke a 350 to a 383. I've seen a 383 in a lifted 98 XJ. It fit fine...He was running a TH-350 and a NP-205 btw...

Go for TH400 and Atlas II (If youre gonna wheel it)

89'XJ · 09-10-2006, 08:50 PM

What would be a good chevy tranny to look for. I've heard good things about the TH-350 but I also heard it kills power.

Cerealdaemon · 09-10-2006, 08:54 PM

if you have to lift the engine some 3 inches for clearance, you might look into getting a cowl induction hood for your xj and chopping material out of the underside. The stock hood may or may not allor for proper clearance, I don't know, but a cowl hood certainly would
