5.3 swap in cj5

well i have been collecting parts for a while and i got the motor on sat afternoon so i figured i would start a swap thread.

specs are
78cj5
t150 trans for now
d20 t-case for now
30 front 20 rear
and i got the motor out of a 07 gmc with 38,887 mi on it.
i will update as i go along, it will be kinda slow going at first with the holidays coming up, i will also be repainting under the hood.

so here are some pics for you now

That's a really clean CJ5. What are you plans in the future for a tranny and T-Case?

Wow, you must be loaded $$$$$...That radiator alone was over $500 wasn't it? One day.....
You should do a little homework on the transmission you want. I always say do it right the first time and never worry about it again. NV4500 would be a nice fit. Backed with a D300 T-case thing would be a monster. You need to address the axles for sure though. Probably will need to look into upgraded axles anyway with a beasty 5.3L in her..

ah no, just sold a bike an my trailer and been saving for about the last yr
nv4500 would be nice but a little big for a 5.
for the most part she will just be used as a "leaf looker" as my buddy says, so for now the axles should be good just need to have some self controle on the skinny peddle.

That would not be a "nice fit" at all.
The NV4500 is way to frickin long for a CJ5.

Since you mention a 4spd....you might consider a SM435 or 465 with an NP xfercase. This will minify (is that a word?) the amount of adapting you will need to do. Plus, the SM trannys are heavy duty vs. the medium duty rated T176.
With the power upgrade, and since you are shopping for a tranny anyways, no point going light on it.

thanks man, well i got the new frame mounts welded in, and got the new motor back out so i can start working on cleaning up the firewall for paint.
on another note i am considering doing a wrangler leaf swap on the front and putting the shackle back in the front like the factory had it, i am kinda tired of it nose diving when i have to hit the brakes hard

well i have got a few things done not much but thought i would put some fresh pics up, i got the lower "lip" cleaned up and put some por 15 on it and wear the fenders go. got the rest of the dash and heater out, started to clean off the old paint, hung the new clutch and brake peddles assembly just need to put the holes in the firewall for the clutch master cyl. i also wanted my motor mounts even on both sides of the frame so i started to modify the AA ones and i cut to much off, so i called a buddy of mine and had his boss make me a new one, came out great. also for Christmas my wife and baby got me a new welding tank so i had to get the welder to go with it any way here are some up to date pics of were I'm at.

Brian whats up man. Great start btw. Just responded to your PM, but I forgot to add that you maybe able to use a drive by wire pedal out of a newer Monte Carlo. It has a flat mounting surface and all you have to do is switch two wires.....

Here is some info: http://www.chevelles.com/forums/showthread.php?t=299469

Although now I remember you saying that you wanted to convert to cable, but theres the info if you change your mind.


Give me a shout whenever you need a hand, seriously would love to come get my hands dirty on that thing.

well getting around to fixing the dents and filling in the fact spot welds now.

also made a block off plate for the orig clutch rod hole, i thought about welding it up but if i want to run some wires or such through the firewall later i don't have to drill holes.

as for putting the clutch master cyl up i had to fill the windshield washer hose hole up, so a made a palate and welded it up, also got the holes drilled.

and i also got all the old caulking out of the upper channel.
