My 5.3L into a Jeep Wrangler

[Chuck21387]

So here's what i started with,

1993 Jeep Wrangler (YJ)
2.5L 4 cylinder (125ish HP)
5 Speed Manual
NP231 Transfercase (Aluminum chain drive)
Dana 35 rear axle (Stock) w/ factory 4.10 gears
Dana 30 front axle (Stock) w/ factory 4.10 gears

What i have to install
2000 GMC 5.3L Vortec V8
700r4 Auto transmission
NP208 transfercase (aluminum w/chain drive) i do have a Dana20 tcase (gear drive cast iron case) that will go in at a later date.
Corporate 14bolt rear axle shaved 1.5" for max rock clearance (cut 2" off the bottom of pig, weld on 1/2" plate, and turn ring gear down 1/4")
Dana 60 front axle both with factory 4.56 gears

Should be a fun toy in the end!!

Sweetness...you gotta own a couple BFH&#39;s...you never know when you&#39;ll need one :-)

So I only threw up a couple pics, i didn&#39;t mention my current state.

I&#39;ve got the new drivetrain bolted together, and the motor mounts fabbed. The engine is bolted in and sitting all by itself&#33;&#33; The transmission mount howevere is still sitting on a jack, but that shouldn&#39;t take long once i modify the stock skid plate (belly pan). I ordered my fuel pump last night &#33; &#33; &#33; And should be in business sooner than i thought&#33;&#33; Thanks to this board and Ron&#33;

I&#39;ll post more pics when i get home after work (Central time)

That&#39;s the goal....hoping to someday be able to roast all 4 tires on pavement....i think that&#39;d be sweet...we&#39;ll see what happens, i&#39;ve seen a guy do it with a 383 Stroker and 40" tall tires, i&#39;ll only be running 35" tall tires...

looking at this picture of the motor placement i hope that you move it back further. there is plenty of room for the factory belt driven fan and a thick aluminum radiator. dont forget that a wrangler engine sits off set to the passenger side 1.5" . the tunnel in the floor is that way also. hear is a pic of the last one i did.
6.0 lq4, 4l65e H2 trans, atlas II transfer case. and the rear driveshaft was still 3" longer than stock.

Thats part of my problem, i&#39;m currently running an NP208 (cause i can&#39;t afford the adapters to the Dana20) so my rear shaft is the same length currently, i&#39;ll have enough room for a 3 row radiator in the stock location (recessed in the grill) and still run the factory fan. :-) Nice looking swap.

So i&#39;m also gonna have to figure out something with a VSS huh?

there is a way to short shaft the 208 case to make a longer driveshaft, but i cant remember the combo. that case was a short fixed yoke in either a dodge or ford, and can be hybrid together. the engine needs to be as far back as possible to keep the front axle out of the oil pan and make room for the exhaust to cross under the front of the pan to the right side. a 2" body lift makes all things easer when placing the engine. the right side manifold fits nicely arround the frame and lower part of the body. i didnt even cut the body. pluss it feels beter off road with the weight back futher in the chassis. they kind of get front heavy and scary going down hills.

I&#39;ve got access to more if needed. You&#39;ll need to have the fuse block pinouts. I&#39;ll have to email those (don&#39;t have electronic copies on file).
