well for us fellow mudders that aint gonna be a problem
Fair enough...Still love the 465 though.
I'm thinking about swapping over to the 465 in my garage, but the only thing holding me back is how often do you stall your trucks? I'm guessing this doesnt happen often, but when it does, is it a pain to get going again if your on a hill??
I stall my truck often enough to learn that I need to get on the gas. I have had to start on a couple of steep hills and it was a little challenging, but not the end of the world. Also, the truth is I stall on hills because my carb runs out of gas, not becasue of the 4 speed. If you ever get do doing it, PM me if you like and I will be happy to tell you in detail exactly what I did. There were several guys on this forum that did that for me and it was very helpful

As NOAHROB said it is usally not the stick tha makes the trruck stall - many things can contribute such as carb's , not enough gear , or an idle set too low.
Throttle controls , EFI . and lots of mechanical gear advantage can cure each of those problems.
If stalling is an issue it is possible to crank the truck in gear with the clutch engaged if wanted/needed. Most folks who do this use a cast iron starter/bellhousing combo though.

Pretty much sums up my experience. Only real differences being the 500 caddy versus the 6.2.
I love it. Doesn't take long to get a feel for what gear ya want and grab it before the obstacle. Let it idle on through.
I can start my 6.2 diesel in gear and it starts as easily and quickly as if it was in neutral. Aluminum nose on the starter, and aluminum bellhousing. That was with 58:1 CR at the time. I now have 100.78:1 so it'll be even less of a big deal. Then again, my truck has never stalled in low range...the 6.2 has a governed idle as well as a governed top rpm, so if I try and pull it down too slow it'll add a touch of fuel all by itself. Makes crawling a dream...feet flat on the floor and do the hard stuff at idle.

Love my 465/205/4.56 on 37s. I will admit that I cheat and use a hand throttle on the shifter...still beats an auto everyday.
The only thing I would change is the 2:1 to 3:1. With a 465 and 2:1, have been in a few spots where 90:1 total was needed

My Dodge will add a touch of fuel if it gets to low of RPM's and acts like it wants to stall. Cool feature but I don't know if the mechanical pump 12V motors have such a feature like your 6.2 does - have you talked with any Cummins equiped trail riders about this ?
I hope to have enough gear to play at idle without fear of stalling but I would like to know if my diesel will do that too.

I'm pretty sure your diesel will do that too. With the amount of torque the CTD makes at idle, combined with the incredible gearing you have I don't think you could stall it. I'd wager the clutch would smoke first.
Even the 6.2 makes a ton more torque at idle than any gas engine. I find it makes wheeling 'elegantly' very easy to accomplish.

I've only owned and wheeled manual trans trucks.
As long as your rig makes low RPM torque you shouldn't have any issues. With a manual, you have to pucker up and just let the thing crawl sometimes and resist the urge to push the clutch in. I've wheeled 22R equipped toys, and they don't stall- even without torque or a granny gear.
Unless you're on mud or sand, or somewhere where you need to shift w/o losing power, a manual trans is the only way to go, IMO. In most cases, you can start in a higher gear and avoid shifting if you're worried about getting stuck with a manual.
You can do things like hand throttle, etc., if you want. But I wouldn't consider it necessary. If you've got even a mildly built rig, you're going to have to be on some pretty wild steep stuff to worry about stalling- and if you do, leave it in gear and restart it. The starter has enough juice.

My SM465 is great for crawling the local malls. I've been known to navigate a few curbs here & there...
Ok I'm done. Carry on.

I love mine, haven't gotten to wheel it on any trails, still finishing the cage and whatnot, but faux wheeling it up a couple big dirt hills we got on the property is a blast with my 6.2 and 465! Oh yes, and I'm not sure if this will help anybody, but it seems like a few people have complained of a sloppy shifter. Mine had the same problem when I got it, and I disassembled the shifter end (drove out the spring pin) and replaced the two o-rings inside. I replaced them with two o-rings from work that fit and gave a nice snug feel to the shifter assembly. Now I am amazed with how short the throws are. Also my trans. is in very good shape, I resealed it and was good to go. Its got much shorter throws than any modern diesel truck I have driven. The throws are much more like a car transmission than a truck, even with that long a$$ shifter. Figured I'd chime in and see if I could help anybody with their sloppy shifting.

It's easy....The torque multiplication of the sm465 vs. th350: SM465 puts over twice the torque down in low gear alone due to the gear ratio.
I took my engine (lightly modded 350V-8) out of my first Blazer that had a TH350/NP203 with part time kit in it. And swapped it into my second blazer that had a SM465/NP208.
Converter slippage would burn the TH350 tranny up going slow. Wheeling fast or with a tranny cooler may work with an auto.
Well, the same engine with the SM465 Blazer, which has a heavier drivetrain feels way more powerful. In low-low it will idle up anything without goosing the throttle at all.

one quick question, i am moving my sm465 with 241 tcase from my 89 blazer to my 82 that currently has a th400 and 208. i was wondering will my driveshafts work? i dont think i need to mod them but i thought i would just ask real quick just to be safe

GREAT thread!
I too currently have the Th350/NP203 combo in my truck, and am NOT impressed with it offroad. But I think my pump may be on its way out the door. And I'm have 3.73's with 35's!
I used to have a '70 K5 with a 465/205 combo. My 1st manual trans. It was fun. But like most of you have said, working a clutch in heavy traffic gets old. And I wasn't experienced enough with a 465 at the time to be confident while wheeling with it. But I do remember stalling issues being a concern on steep inclines.
Didn't know about the tricks you all talk about.
For what its worth... I'm 99% decided on a 465/205 swap.
Question though:
For 40"-42" tires, what ring and pinion can someone recommend for me? My truck will see stretches of highway from time to time. But not all the time. I would like to go to Moab, for instance, someday!!! And its a 5-6 hour drive on I-70 through the mountains from where I live.
Would 4.88's be a good choice for wheeling and still okay for highway RPM....
Anyone here running 42's with a SM465 at 65+ mph?
