Health and Performance The 6.2 snaps cranks, cracks blocks and heads...makes about 160hp but gets 18mpg The 8.1 is so stout it survives a 300 hour dock test so it's used in boats, generators, medium duty trucks, and in the Chevy lineup...makes upwards of 500 foot pounds of torque stock but...

I have two major issues. The gear vendors unit still utilizes an although strong but pretty useless stock TH400. Tall first gear, power sucking non-lockup converter, and no OD. So $3k plus driveshaft refit, you could do a really nice 6.0 swap for that money using all OEM stuff. The 6.5 swap or...

No idea on mileage, I haven't taken it on long trips yet so I don't really have any data. I just smile when I fill that 40 gallon tank. The 4L80 is run off the factory 8.1 ECM. All stock just like a big block Avalanche, Suburban, or Express Van. Yeah I get it. I just took the M1031 today on an...

I will tell you that I love my 6.2 M1031 but I have written it off for anything but an around town run about or errand runner. The noise, stench, speed, and sluggishness really detract from wanting to take it on long hauls. Don't get me wrong I love it this truck. Just finished up AC so I can...

I bought it off Amazon. Mine is a Four Seasons. Mixed reviews online, some had premature failure. The genuine Delco one is like $700 so I rolled the dice at $300. Of course compressor seizure could be bad pressure switch or lack of oil so I'm not going to worry about it. The factory A6 is a...

So my left over M1010 accessory brackets got put to work on my generator truck. I did a 12v conversion at the same time bit could have stayed 24v just by adding a second alternator. I absolutely disliked the aftermarket bracket solutions for the normal CUCV alternators. This is why I went with...

That is the governor which pushes on the throttle, generator has to run at a fixed speed. Only the cool kid M1031 get it [emoji16] Sent from my Moto G (5) Plus using Tapatalk

I am in the middle of taking my stock M1031 setup and swapping it out for my old M1010 drive. I am going 12v so Leece Neville 555JHO on the passenger side, bolts in. I was going to reuse the factory Fridgidair compressor as they are rugged and pump a lot at idle...but...they suffer from crank...

First post back after many years! M1010's are cool but man do they suffer from neglect in the electrical department. I think you really need to figure out if you want to stay 24v or go 12v. Cannot proceed until you make that call. 24v is awesome for cranking power, jumping the other CUCV's...

Hey guys I live in Kittery area and work in Westbrook. Looking to rent space somewhere between those points along I95. I have a CUCV M1031, a matching Suburban, and a Samurai. I'd like a big enough space for one if not two of them inside with a toolbox. All vehicles are registered and...

What do you want to do with it? If you want bigger tires and offroad capability it will probably pay dividends to shorten it up. You gain everywhere. If its for general use you get into too short of a wheelbase to haul, stop, or carry anything which makes it useless. No one is swapping in one...

First I would not bypass the safety switches. They are easily obtainable and really keep things from getting messed up. Spend a little time cleaning and adjusting here. As for the rest of it, my recommendation is stop wasting any more time with it and just spend the money for the controller...

I would also check the rivets on the frame. The 2wd Suburban I converted to a CUCV clone had some loose ones up front that were tough to see. The rivet worked loose slightly and elongated the hole in the crossmember. These big floppy C channel frames like to work themselves loose over time.

I run the HD springs in my M1031 and Burb too. They are a good match for the heavy diesel, ride is good for a straight axle truck, flex is great, and they are pretty affordable for an off the shelf spring. At minimum you will need the usual shocks and brake lines. You can buy the ORD braided...

I think Dodge guys have fluid issues (and Jeep) because the NV3500/3550 and NV4500 both require a special New Venture fluid that you get at the dealer. I believe there are only a handful of other fluids that will work, Royal Purple and Pennzoil Synchro something are known compatible. Any other...

So then why are stating an idea like putting gear lube in an auto trans which is complete rubbish? This only creates confusion and clutter. NP205 runs on ATF or 75-90, end of story. Only the short bus usual suspects on here have to create a freakin science project out of something so...

Would an automatic run on gear lube? Apparently you have never taken one apart then. An auto trans is not just gears and bearings. It has friction discs which are engineered to work with a specified fluid that has a specified friction which guess what...works specifically with the friction...

It's a set of gears and bearings...pretty sure it will be happy with any lubricant in it. The 205 will accept either one and be happy with no ill affects. So I'll throw a bone into your explanation. The T5 Tremec 5 speed came off the line with gear lube just like every other manual trans in...

The ol' M1010 had too much metal work to be done so I had to do the nasty and gut her for the running gear. I did save the box just incase I want to repurpose it somehow down the road. I decided to build a Suburban CUCV/Dante's Peak clone. It's almost done, just lots of little things to be...

Convert whatever the oil cooler line fittings are which I think are O-ring on the radiator and flare on the engine but that's off memory. You buy adapters to go from those to whatever size line is required and make the lines yourself.
