6.6L LLY Duramax Short Block Engine

This Build Includes:

– Full CNC blue print machining, (bore, deck, hone and line honed) – The Cylinder bores are blue print bored to a true 90 degrees from the crankshaft center line, prior to being diamond honed to within .0002″ for precise piston to cylinder bore clearances. We main bore and line hone the crankshaft which is honed to precisely align the crankshaft in the engine block. We bore the block back to the crankshaft center line and hone the block to RA13 finish. The piston diameter measured to the nearest .0001″ matched to cylinder bores. The Cylinder block is surfaced to a finish of RA30 or lower, which meets the factory specification in both flatness and smoothness for the block to head sealing surface. This is mandatory for proper sealing of a MLS Gasket.
