New AM General - GEP Optimizer ™ 6.5L Diesel Engine - Side Mount Turbo Truck & Suv
This is the latest version of the 6.5L engine still produced new today. These are build-to-order engines in that your engine is run down the assembly line after order. Unfortunately, they are not built ahead of time and stored. Standard lead time to delivery is approximately 6-weeks, sometimes less depending on assembly plant's load.
This engine can replace virtually all 6.5L side-mount turbo applications used in 1992-2002 models ranging from trucks, Suburbans, Blazers, Tahoes and more.

Engine Preparation Options
If unit is being shipped via Air Freight the engine must be free of oil, new engines come with break-in oil in the pan, so engine must be un-crated and drained of oil and a new filter installed (that is dry). This requires being sent to Unique Diesel for processing making it not possible to drop-ship from factory, this is part of the cost associated with this option.
Addition of timing tab for mechanical engines. The factory cannot modify this assembly as it's intended for electronic engines. We can optionally add the mechanical timing tab to the front of the engine's timing cover with special tooling and have it match TDC for timing with timing lights, We do this and add the plug in the timing cover to delete the crank sensor opening. This makes the engine have to come to us instead of being able to drop-ship. This is part of the expenses figured into the cost of the option.
