mj 6.0 swap on tons
1 Attachment(s)
Picked up an 89 mj a few months back.2wd short box with a 4.0/5spd. Very little rust. Paid 1400 for it with 97k. I bought it with evil intentions. Ls engine, Muncie trans, 1tons, and 37"+ tires.

Iv already got motor and trans. 6.0 truck engine running just shy of 400 HP stock. And a 4 speed to plant it. Already pulled the 4.0 and started the engine bay cleanup.

Motor mounts from Novak should be in Saturday. Picking up an intake later today for the engine. Little back story on the engine. It's a 2008 ly6 6.0 truck engine with 8,000 miles on it. I picked it up for $130. The reason is the block is broken on the drivers side lower bell housing bolt. Good thing I'm a welder and know plenty of people to get that fixed up easy. The plan is bigger injectors, cam, some valve train work, and headers. With that I should be around 400. These engines ran approx 380hp stock. I'll do my best to keep this thread updated.

Alright so iv been going back and forth about my trans choice. Iv got an sm465 (4 speed Muncie with granny low) that I originally planned to run but I'm worried that this will make it obnoxious to drive on the highway for long trips. Do I go with an nv4500 or put lower gears in the axles to make up for it. Remember I'm running over 400hp in a truck that's going to weigh around 3000lb

absolutely nv4500... do it right the first time. you will almost certainly have to hack the tub to fit it in there...but you wont have to worry about it ever again.

do you have axles yet? if you aggressively follow the axle classifieds on pirate you can find anything you want in the one ton category. i just picked up at 97 hp ford 60 complete for 750 with 4.10s...

what transfer case are you looking at?

mckoolkid 01-14-2014 01:04 PM

I'm looking at a Chevy 203. The only thing I'm worried about is trying to find a 4500 for a decent price. Axles I'm not worried about yet. Just trying to focus on the drive train right now. I know enough guys in the area that have axles laying around

you got 700$???????

mckoolkid 01-15-2014 12:45 AM

Seems like allot for the mileage and synchro problems. Are there any other options other than a nv45 that will give me a decent highway gear and still hold up?

Solidkm 01-17-2014 09:31 AM

another option...?

MOBBiN 01-17-2014 12:52 PM

I'll be watching!

mckoolkid 01-17-2014 01:01 PM

Based on calculations from this website.
With a 4.10 axle ratio and a 40" tire and the Muncie 1-1 final drive I'll run around 2400rpm at 70. I think I might be ok with that. I'm still tossing around a nv45 but right now I don't want to spend the money on it.

Solidkm 01-17-2014 01:51 PM

what about a 3550? low first gear, right? and it has a decent reputation. i dont know how abusive you plan on being
