This engine fits 1996-2006 Hummer H-1 and AM General HMMWV trucks w/ GM 6.5L Turbo Diesel (Rear/Center-mounted Turbo). This is a re-manufactured engine using Genuine AM General / GEP Optimizer™ / Navistar™castings..... the ones built after 2004 with the better castings. This engine will also fit all GMC and Chevy Express vans with the turbo 6.5l engine. Fits: Center-mount or Rear-Mounted Turbo applications, (H-1 Hummers , Vans & some RV's). For over 21 years now, we have been involved with the 6.2L and later the 6.5L engine exclusively. Check out our Feedback! People love our products and service! Some other companies are selling new block/head engines, but be careful, most are new block/heads using the old casting forms, no improvements - FROM CHINA! . Booooo! There is only a handful of others offering IMPROVED & UPDATED castings aside from AM General and General Motors themselves. The design improvements and re-engineering of the improved castings add durability and virtually eliminate the potential for cracking in both the block and heads. Here is What is New and Improved about our Engines: These Engines Are Built Using the 2004+ Optimizer™ / Navistar™ Improved Block & Head Castings. Our engines also include major improvements to the oiling systems, including our exclusive: High Volume & High Pressure Oil pumps. BLOCK & HEADS: The iron used in the new block utilizes molybdenum, a metal yielding a 20-25% increase in strength, without being brittle. The new block design also incorporates improved main bearing webs and caps. In addition, the head bolt holes in the block deck are strengthened, vastly improving head gasket durability. Additionally, changes of the water jacket design in the heads have helped address the 6.5's overheating problems. The original 6.5 & 6.2 cylinder heads produced by GM were prone to developing small cracks between the valves. The new redesigned heads have added chromium to the cast-iron to virtually eliminate these and other cracking issues. The Optimizer™ block and head system offers complete parts interchangeability & bolt hole alignment as your original block. OILING SYSTEM: This engine also gains improved durability & longevity with a High Volume / High Pressure oiling system. INTERNAL COMPONENTS: We use MAHLE Clevite branded internal parts on both our new and remanufactured offerings. These are top quality parts from a well known industry leader. AM General and GM both use/d MAHLE as the O.E.M. internals. Mahle Clevite has significantly improved both the Pistons and Connecting Rods since the time that the 6.5 was used by General Motors. The Connecting rods are more durable and the Pistons are stronger and lighter. With these important improvements, the BMI 6.5 is among the toughest 6.5L diesel engine available today. We have have been selling the 6.5L engine with new improved castings for more than 9 years now with great over-the road success.Now we can offer the Real Optimizer™ castings! Not one block or head crack issue to date. - Now that's what we mean by an improvement. Compare to others: Our longblocks come with already installed; Valve covers, Oil pan, Oil Pickup Tube, Timing Chain Cover, New Harmonic Balancer. Every one of our engines are hot-run in on the dyno after final assembly. During this time the camshsft is properly broken-in, the and the engine is monitored for any sign of oil or coolant leaks. All of our engines are dyno tested. This is why we do not offer short-block engines, Short-blocks can not be adequately tested on the dyno. Be assured with our Unlimited Mileage, one year warranty covering every engine we sell. You expect hard work from your diesel powered truck, and we'll guarantee it. We are proud of our long track record with the GM 6.5 Liter Turbo Diesel engine. We do not take shortcuts during the manufacturing process. Please state year make, model and 8th character of VIN code when ordering to be sure we build the correct engine for your truck. There is a Core Deposit that will be refunded when rebuildable core is received back. Any of your core's deficiencies can be pro-rated and may not necessarily mean complete forfeiture of core deposit. Let us know when the core is ready, and our freight company will pickup the core. We pay the return shipping for your core. Our domestic long-block core deposit is just $500, not $1000. like some other companies, however the $1000 core must be charged for overseas buyers.
