Like the 6.2L, the 6.5L diesel was available in 1/2 through 1 ton pickup models until its retirement following the 2000 model year. However, the engine platform was not retired entirely - Humvee manufacturer AM General continued the 6.5 diesel's legacy under license from General Motors. Unlike the 6.2L, the 6.5L was produced in both naturally aspirated and turbocharger versions, the latter providing significantly more torque.
In 2019, we celebrated a 30-year partnership with RAM truck that started with the Cummins 5.9L Turbo Diesel in model year 1989 through our latest 6.7L Turbo Diesel. The latest 6.7L Cummins Turbo Diesel brings to the table more horsepower and torque, improved NVH and reduced weight. Oct 03, 2007 FWIW, I'd invest $20.00 in a Haynes Diesel Engine Repair Manual #10330 or the like. No way would I attempt a total rebuild without a manual, if for nothing other than the torque specs, just not worth the risk IMO. I'll list what I can as it pertains ONLY to the '96 6.5TD but dont assume its all correct, READ verify these numbers!

Many variations of GM's 6.5L diesel were produced, including a special 120 horsepower (260 lb-ft) model specifically for delivery trucks. The most powerful version of the engine used in GMC/Chevrolet trucks was a 215 hp, 440 lb-ft, turbocharged model. For Silverado and Sierra pickups, the engine was backed by either a 4L80E 4 speed automatic transmission (with overdrive) or the popular NV4500 5 speed manual transmission. Common problems with the 6.5 diesel include crankshaft, glow plug, and PMD failure. Overheating is also an issue with the 6.5L, and it can lead to cylinder head cracking. In essence, the 6.5L Detroit diesel was a leap above the 6.2L, but it's generally accepted that the engine was outpaced by Ford's Power Stroke and Dodge's Cummins turbodiesel offerings.
The 6.2L diesel was introduced for the 1982, following the retirement of Oldsmobile's 5.7L diesel. The 6.2 was manufactured by Detroit Diesel, a division of General Motors at the time. GM never intended for Detroit's 6.2L diesel to perform the heavy lifting. They wanted an engine that could haul hay to, from, and around the ranch while consuming as little fuel as possible. Additional, the robust design of a diesel would mean the engine would outlast a comparable gasoline engine. Properly tuned and maintained, the engine well known for achieving fuel economy figures well into the 20's; impossible to beat with a small block V-8 or even V-6 gas engine of the same era. Being naturally aspirated (a turbocharger was never offered as OEM equipment), the 6.2L diesel has a relatively high compression ratio. The heart of its injection system is the Stanadyne DB2 injection pump, the same pump used on the 5.7L Olds, International's 6.9L/7.3L IDI, and the later N/A 6.5L diesels. 6.2L diesel engine block's and cylinder head's were produced from cast iron. Interestingly, the engine was offered in 1/2 ton, 3/4 ton, and 1 ton GMC/Chevrolet pickups, as well as Blazer and Suburban models. As a result, GM is considered the original pioneer of the 1/2 ton diesel in the United States, although credit is often given to Ram Trucks for the introduction of the 'EcoDiesel' for their 2014 model year Ram 1500 pickup.
The original 6.2L came mated to either the TH400 three speed automatic, Muncie SM465 four speed manual transmission, or New Process NP833 four speed manual overdrive transmission. The 6.2 shares its bellhousing pattern with GM V-8 gas engines - a diesel transmission will bolt up to a gas engine with no modifications and visa versa. The diesel automatic transmissions typically used a different torque converter than the gas engine automatics, although there seems to be some exceptions (which relate to the truck's GVWR) in which this is not the case. If swapping transmission from gas to diesel, it is best to acquire the torque converter specific to your application. The Muncie SM465 is much more common than the New Process NP833, which features an 0.73 to 1 overdrive in comparison to the SM465's 1 to 1 top gear. The NP833 can be identified by transmission RPO code 'MY6'. Later 6.2L GM diesels were available with the 700R4 and 4L60E overdrive automatic transmissions as they became available and were integrated into their platforms.

The 6.5 L (395 cu in) version was introduced in 1992 to replace the 6.2. Most 6.5s are equipped with a turbo. This engine was never meant to be a power and torque competitor with Ford/International and Dodge/Cummins, but rather a simply designed workhorse engine that made credible power, achieved decent fuel economy and met emission standards in half-ton trucks. 6.5 Turbo Diesel Performance. 6.5 turbo diesel performance is one of the things that makes owning one so worth it. Not in stock form necessarily but with the ease of what amounts to bolt on mods. In stock form and in well maintained shape, the 6.5 can give reasonable performance for a daily driver or occasional hauling. Apr 11, 2016 has a great set a of battery cables t.
The 6.2L diesel was ordered with regular production option codes (RPO) LH6 (C series) and LL4 (J series). Many vehicles employed by the United States' Army were powered by the 6.2L diesel, from pickups to HUMVEES. The Army version had a higher output rating of 165 horsepower and 330 lb-ft of torque, quite an increase over the production engines. While there are a number of high mileage examples, the 6.2L suffers from many reliability issues, including cracks forming and propagating in the engine block, flywheel, harmonic balancer.
Overall, the engine has not been particularly popular, but had its place in the market and a moderately sized following, even today. A popular trend is to acquire an 80's 6.2L diesel powered half ton and swap in a built gas engine. The 1980's diesel chassis does not require any emissions inspections in states that require periodic inspections, and fans of the 1973 to 1987 body style can modify the trucks as much as they want without running into registration issues. This is an alternative to finding a 1975 or older chassis, which limits the pool of trucks to choose from (pre 1976 trucks do not require SMOG inspections in CA and states with similar laws). If searching for a used truck powered by the 6.2L diesel, it is quite common to come across ads for trucks that have undergone such transformations.
