Towing with a 6.2

[Duntz00]

I am planning on using my 82 3/4ton with a 6.2/sm465/208 and 3.73 geared axles to pull my trail rig around, I know it won't get there fast but will it handle the load. The trailer is a 20ft bumper pull and when I get my trailer done it will be a 23ft bumper pull. Im wanting to swap a nv4500 in but don't have the money for that at the moment.

It'll do it, but these engines are not built for that kind of duty. I'd suspect it won't last very long if you work it real hard under those conditions

That and as far as the tranny goes the NV4500 won't help it tow better either.

I am planning on swapping a cummins in after the 6.2 lets go, Ive got $500 in the truck so it ain't going to hurt my feelings if the motor don't last long.

Then by all means -- Crank that pump up and giver' hell! I'd be interested to hear how you feel it does!

I bet it spits the crank out..........

I might would do that if I got a cummins sitting in my garage but I don't know if I could blow up a perfectly good motor like that.

I ain't going to try to blow it up but I am going to pull with it and I know its not a new diesel so I Im not going to push it to hard because it gets the same if not better fuel mileage than my DD.

IF (and I mean IF) the 6.2 is going to hatch it won't matter if you're towing hard with it or not. Broken cranks and main webs are really long-term durability issues, not short term ones from working the engine. Besides, in the overall scheme of things that failure really isn't that common. It seems that a GM 6.2 or 6.5 will either crack a main and fail within a few 100k miles, or never crack and run forever.

I've towed over 6000lbs several times with my 165HP J-code 6.2. It actually did ok - I was more worried about my poor 4L60 trans. That's why I plan on stuffing a 465 in there

My "J" code 6.2, Th400 and 4.10 gears does fine towing just about anything on flat ground and i mean flat ground. Towing the setup in the picture up a hill works the pi$$ out of it

Nice. I've never towed anything THAT heavy, but I know the engine will do it. You just have to be patient on the hills.

What annoys me is that my current gearing has an area between 48 and 60MPH that is too tall in 3rd (1:1) and too short in 2nd(1.7:1). When I went hunting in October I had the back of my Blazer loaded with gear AND an 8ft trailer loaded up (were talking firewood, LOTS of water, extra fuel - heavy crap) to it's 3500lb limit. Total load was probably 4k, plus my truck which scales in at around 5900lbs, so about 9400lbs total. The grades going past Mt. Ord to and from Payson has some long 7% climbs, as well as the 6-7% on Highway 260 climbing the 7600ft Mogollon Rim. The truck wouldn't hold 3rd, forcing me to downshift to 2nd. 2nd would sit at 48MPH running against the governor Even at 7000ft where the NA (NA=Needs Air ) motor was wheezing! I know I had bit more motor, but I couldn't use it because of the gearing and/or the fact I was stirring a torque converter and pissing away some of my HP

I have an SM465 to fix that though... not to mention a set of 6.5 turbo manifolds and a whistler
