Finally on something lol.
I actually had a 1998 chev with a 6.5 and the 4L80E that had over 600000kms on it when it blew.Had it rebuilt by a local tranny shop and the guy figured we should dip it in gold an send it to GM to hang on a wall somewhere as the only one in exsistance to ever get that high.
The work truck I have now is a 2006 2500HD 4x4,duramax/allison and I love it.
Great on fuel,lots of power and great combination of truck and drivetrain.

I will have to agree with some who say that would be a bad idea,the 6.2/6.5 are a fair bit heavier then the sbc,the fuel economy that you would gain would be far outweighed by the extra weight of the engine.Specially the first time you had to replace the fuel shut off,or the injection pump that would be worth more then the truck its in.
They lack any performance of any kind,you can do a little to them to perk them up,very expensive,I have had a couple late nighties chevy trucks with them in it.
Heath diesel in Washington has done some cool things with them,but spendy!!!
The 6.2 is best used to hold your boat in place,they are not now,nor were they ever any good for anything other then decent fuel millage in a heavy duty,light truck.
Pull the heads from anyone that the crank magically never broke in and you will find the pre-combustion caps stuck to the headgasker rendering the expensive head scrap metal.
The 6.5 are better by a long shot,still not anything worth swapping for other then an ancor.
Sbc swaps are cool,they do have their advantages,more torque,power but much more weight.
I like the idea of engine swaps to a diesel,I am a diesel mechanic by trade,but there are very few engines that I can think of right of the top of my head that would fit,or would be practical in a small truck.
Diesel engines are heavy,the 6.2/6.5 are no exception,the are based on the olds/buick 350-400 engines not the sbc.the bell housing isn't the same.
Spark plugs...$3.50 each times 4...22RE
Glow plugs...$25.00 each times 4 on a 2.4,or worse times 8 on a 6.5
Injection pump (if you are lucky) $1200
I would say stick with what you have.
Thats my opinion,and you know what they say about those lol.

The Diesel 6.2 6.5 are not based at all on the olds and buick 4.3 V6 diesel and the 5.7 V8 diesel. And the bellhousing IS the same SBC bolt pattern as all the GM SB bellhousing bolt pattern. I know because when I got mine I had to have the tranny rebuilt, its a TH400 and it is the best 3 speed GM tranny, I think it failed due to being a Jasper unit.
Now the 6.2 is ALOT bigger in both size and weight then a SBC, the motor mounts are the same as a SBC.
A good injection pump is $700 US.
Glowplugs: it depends on what ones you get, I recommend AC 60Gs, and yo don't have to replace then nearly as much as you do spark plugs.
You are right on the 6.2 being fairly gutless, but it tows alot better then people think, and you can do alot to boost power in such a small truck.
And the 6.5 really isn't THAT big of an improvement over the 6.2. Its just a 6.2 with a slightly bigger bore and a turbo with a slightly higher flow rate injector pump and injectors.
Some of your information is correct. However some of it is not.
A mechanical injection pump for a 6.2/6.5 is about 500-600 bucks. Even from Healthy diesel.
Glow plugs are about 10 bucks a peace not 25. If i remember i replaced all 8 of mine for 69.99 but its been about a year.
The 6.2/6.5 where a far improvement over the olds 350 and share very little in common (it was a true gm engine) And i am about 90% positive that it is a GM bell housing.
And i still would question the weight vs a SBC. As well since i have not seen any proof that the Detroit is that much heavier. You will add a few pounds for the injection pump but the cylinder walls are not that much thicker then any other SBC. Guessing maybe 50-75lbs at the most.

I love my 6.2L diesel, just as much as I love my 22RE(if not more, its a 1ton truck that gets almost the same mileage with 4.10s and a 3spd auto vs a 1/4ton(maybe) with a 4cylinder 5 speed and 4.10s)
That being said. I think it would be a cool swap. but you're going to want a solid front axle with really beefed up front suspension to handle the weight. And you are going to have clearance issues, I'm thinking small body lift, and some pounding on the firewall.

The 6.2 weights about the same as a big block.
I have one in my CUCV that I put a TH700R4 and proceeded to grenade over and over until the trans shop figured out how to boost mainline pressure at idle to hold against the torque.
They are a "joke" in the diesel world but was what GM needed in the 80's to compete against the other two.
I had a REAL Detroit Diesel in another truck for a while. It was a 4-53 NA with a Clark transmission. Talk about heavy!

NOW the 4-53 with a Clark, THAT is a real Detroit!
