And how or what do you compare those engines to a 350/454?

What are everyone's past and/or present with the 6.2 and 6.5 Detriot Diesel Engines?

My 6.2 is still in my truck.
I don't think you know how forums work

No lol. I meant in general
got 2 and like them. with a turbo its close to a 350 for power
But with better mileage.
I have a 6.2 in the CUCV. I love the simplicity of it. It's like a dirt simple EFI setup that's totally waterproof. Well, dirt simple if you ignore that injector pump thingy, I have no idea what's going on in there. I put it in the same category as auto transmission. 
Nonetheless, it feels really reliable and simple. If I had my K5 swap to consider over again, I'd seriously consider putting one in. Main downside is that there's not much acceleration, and it's easy to get the RPM too high at highway speeds, plus it's noisy as hell if you open the hood while it's running.

First off,Detroit Diesel ,a division of GM,only "designed" the engine..they are not a true Detroit,regardless of what Wikopedia says..
I own 2 of them,am not really that fond of them,but I dont hate them either...both have about the same power and torque as a straight six does in natuarlly aspirated form (no turbo)...
The have their weak points,they aren't like a "true" heavy duty diesel like a Cummins ,but were intended to be fuel savers compared to gas engines..cant prove it by me though,my 3/4 ton only gets 15-20 mpg most of the time empty or loaded,and more often 15-16 than more..a gas powered EFI truck will equal or beat that,using cheaper gasoline..and feel more powerful in typical city/highway driving..at times the 6.2 can feel gutless,like when you need to boot it up to 65 mph merging onto a busy highway..it can tighten your sphincter !..
I don't think I'd want to tow anything with one,not far anyway,or up hills..
They were noted for having crankshafts fail early without warning--some blame the harmonic balancers for that problem,but I have seen at least 3 that snapped a crank and had good balancers on them..
I think they just didn't forge them well enough..they also are noted for head gaskets blowing and heads having problems with cracking and oil leakage at a casting port..but not every one is going to snap a crank or pop a head gasket either..most of them hold up well under daily street use..
While its true a diesel requires no "tune ups" since it has no spark plugs,wires ,distributor & cap & rotor,carberator,etc,they do require frequent oil changes and filter changes,glow plugs cost 80 bucks a set or more,and overall,most of any "savings" goes away when it comes time to repair an injector pump or other repairs to the fuel system..
The way I use my truck just for a daily driver,and driveway plower,dump runner,I would be just as happy if it had a straight six or gas V8,big or small block,it would be as cheap to run,probably easier to fix,and since I am more familiar with the old school engines,I'd feel more confident..
I have never had a 6.2 "apart" and the injector pump and timing chain,and water pump appear to be a more intimidating job to perform than to do them on a gas engine..however,in the 12 years I have owned my pickup,I have not had to do much of anything to it "major",and I cant bitch about it's reliability..still has what appears to be the original water pump and many other parts,it was a salvage yard engine someone installed before I got the truck,that supposedly had only 80K on it,but who knows..
I just wish it didn't sound like a piston is going to come apart,its always sounded more rattly than the 6.2 in my Burb ever since I've owned it..every time you drive it you wonder it it'll come apart on you..but a lot of guys who owned one says that is "just the way they sound,its "normal"....
There are other issues with diesels too,if you live in a cold climate,they can be hard to get started if you dont keep the glow plugs working and plug in the block heater when its below 20 above...you don't have that worry with a gas engine..

Well, I've had all four (350 TBI & carb, supercharged TBI 454, 6.2 with Banks turbo, 6.5). My favorite of the bunch, hands down, is the 6.5l - for my usage it's the best combination of power, fuel economy, reliability, and drivability (it takes the win because of the wastegated turbo).
I wouldn't much want to drive one without a turbo - naturally aspirated diesels of any flavor are just plain dogs.
The key to the 6.2/6.5 series is knowing the necessary checks/mods for reliability and implementing them. It's not uncommon at all for these engines to run 250,000 miles with the right mods and maintenance.

I have no idea what the question even is.

I think he wants to know i you've ever received a 6.2 detritus engine as a present and how well a 350-454 will run off diesel?

About past experience with a 6.2 or 6.5 diesel
Well, I've never owned one, but my experience with them consists of stupidly clicking on never ending threads that go nowhere, about them.

Sooooooooo...why are there so many never-ending nowhere-bound threads on this topic lately? Seems like most folks with opinions have already thrown them out there by now...
Well that settles it, we simply need another thread that is nearly impossible to read/understand about the 6.2/6.5.Sooooooooo...why are there so many never-ending nowhere-bound threads on this topic lately? Seems like most folks with opinions have already thrown them out there by now...
This is fun to watch.
On another note. I have never owned a diesel until now with my current 6.5. I like it.

We could just keep this thread as a sticky. The title alone is enough to accomplish a ton of confusion. Id start a new thread but i dont own any diesels yet....
maybe we could call it "6point2 detritus's and other non sequitur" lol
maybe we could call it "6point2 detritus's and other non sequitur" lol
I'm pretty sure the O.P. doesn't own any diesels, either. And I'm thinking he won't ever own as many diesel vehicles as he has diesel threads.
Confusion accomplished.
