2011-2016 Chevrolet GMC 6.0L V8. w/ V.V.T., No D.O.D., Cam Cast #6660.
This engine engine comes as a long block with the oil pan and timing cover installed
We have improved this engine with the following components
- Hypereutectic side skirt coated pistons to reduce
- Improved flow oil pump due to higher output volume
- newly improved valve seals to promote longevity and overall reduction in oil consumption
- utilize M.L.S. multi layer steel head gaskets to strengthen head to block sealing
- New TTY torque to yield head bolts installed on every build to improve head clamp load and prevent gasket failure
- multi angle valve seat resurfacing on CNC equipment to improve valve sealing
- Improved rod and main bearing design
- improved piston wrist pin design to eliminate the dreaded LS tap or knock
Every engine we sell is fully remanufactured to meet or exceed OEM specifications:
- Deep Clean – To start the remanufacturing process, every engine is fully disassembled and hot tanked (cast iron) or thermally cleaned (aluminum)
- Inspection – Magnaflux testing uses magnetic particles to inspect metal, checking for microscopic cracks and fissures that will cause long-term failure. All parts are visually inspected as well.
- Machining and New Parts – Deck surfaces are CNC machined and new parts are added. New parts include bearings, pistons, rings, lifters, oil pump, gaskets, Viton™ valve seals, freeze plugs, galley plugs and either a new timing chain (with new tensioners) or a new timing belt (with new tensioner). If an engine has a timing-driven water pump, a new pump is installed.
- SIM Testing – Each engine is SIM tested after reassembly, with the cooling and oil systems being fully pressurized and the crank being spun at high RPM to verify compression and build quality.
Every unit is fully remanufactured and covered against defects in materials and workmanship. Email us to confirm the current warranty term for this unit before purchase.
