What are the pros and cons of the 6.2l diesel?
I am looking to put one in my Frankenstein but I want to know what you guys think of them? Can they handle a truck like this?

That truck is very unique. Looks like it started as a panel and was converted into a long carryall/suburban. 64-66 bodystyle. I know that the long WB panel was never a factory 4x4 option. Do tell about the truck. I'm the former owner of a 62 GMC factory 4x4 panel truck. Oh, the 6.2 would work quite well in one of these, albeit a little slow. Not slower than a 305 V6 or the inline 292.

That truck is a 1966 gmc coach it is (I have been told) one of 3 made in 66 it was a bus it had bus windows and bus seats (4 rows of 3 I believe). My dad acquired it from the guy that stripped the buss stuff out and made it 4x4 (it is cool as a 4x4 but this truck I would rather have had original) he drove it for years but had to park it about 5 years back and he wasn’t happy about it but that’s life. So a year ago when I sold my baby (my 52 m37) I needed a new truck to spend money on so I started working on this. It has lots more work to be done but it has come a long way since we started working on it and “fixing” all the “rigged” modifications. We plan to start the last of the bodywork (we replaced the rockers worked on the fenders and doors) and replace the back floor (wood) in a few weeks (give of take a month). The truck has a 472 out of a Fleetwood Cadillac so it sucks gas like its going out of style but it will smoke any other truck off the line. But since fast ant what im looking for and I love the smell of diesel I am looking to swap it out. A 4 or 6bt would be my first choice but it is also the most expensive. So im hopping some guys will chime in on what they like about the 6.2. How slow are we talking? If it can do 65 im happy but I have never had a 6.2 so I just don’t know.

Well speed depends on gears. Since you got the engine picked out.My uncles wrecker could go 85-90 but he had like 2.??:1 ratio and the 6.2 Vs. A m1008 with 4.56:1 ratio and tops out at 55 or so.

 

[deuce_09]

That truck looks cool. I've never seen one like that.

Do you know what axle you've got in it? Or the ratio?
The transmission?

 

[deuce_09]

A pro for the 6.2 is mpgs are around 20 a con is that they don't have much pullin power unless you spend some money.

My M1008 will pull a house , it is not fast but it will pull and haul a ton with ease

you can get 200HP out a a 6.2 for about 100 bucks. if you get the gearing correct for what you are going to use it for a 6.2 is a stront engine. Now we are not talking a 454 here, but good power with good fuel milage.

 

[bubba_got_you]

it has a dana 60 rear with i think 4:10 I plan to change the transmission with the motor because the one that is in it now only has 3 gears. I want more gears with an overdrive. what transmission would work good with the 6.2? i was thinking along the lines of a R 700 but i heard they are week.

 

[Westech]

700 were junk for the first 4 years, after that there a good trans. If you get a rebuilt unit your safe. Ony thing is you need to get a trans that is set up for the diesel engine. DO NOT put in a gaser 700 and think its going to be perfect.

I know they pull. Maybe I said the wrong thing.this was more my thoughts: A 6.2 is no cummins powerstroke or duramax. YOU can pull more cuz of the setup.m1008's are beasts. If only they had duramax's...

 

[deuce_09]

You said you want it 2wd? You want unique? Can you drive a standard with ease?if so,I got a crazy idea..

 

[deuce_09]

I hear alot of people find 6.5 diesels and put all goods on the 6.2..
They do that because the 6.5 block cracks between the cylinders if it gets too hot. And this was a bad problem with them. But I've been told that is cuz the bore and/or a little hole cast between cylinders. I was told too that there are places that will put a piece of solid metal in that hole and It helps alot. IMHO people crack diesel blocks and fling rods and go through pumps all for one reason, hot roding. Be easy with it and it will treat you right. I've go a friend who's dad has a 97' cummins with 600,000 mi on it and is still goin. All highway. I'm sure he replaced parts by then..

Only thing I don't like about the 6.2 is lack of acceleration up hill on the road. Then again, I am running 42's with 4.56 gears in heavy M1028a1.

Off road, the 6.2 is nothing to shake a stick at in 4 low, I love it when it comes to that.

I'm also getting around 16-18 MPG with 42's and 4.56's, can't argue with that.

 

[deuce_09]

Is that 6.2 stock?

 

[DokWatson]

Is that 6.2 stock?

Mine? Yes, as far as I can tell it is stock. I'm not the original owner, so things may have been tweaked here and there.

Free flowing exhaust is the only 'modification'

 

[dragonman]

200 HP how

you can get 200HP out a a 6.2 for about 100 bucks. if you get the gearing correct for what you are going to use it for a 6.2 is a stront engine. Now we are not talking a 454 here, but good power with good fuel milage.

Hello how do I get 200 HP for $100?

 

[Cucvnut]

I think westy means you can get 200 total hp for an extra 100 bucks not an extra 200 over stock

 

[DokWatson]

I'd also like to know how to get a total 200HP for 100$

 

[deuce_09]
