I have a salvage 5.3L GM engine for sale. It was removed from a 2006 GMC Sierra pickup with 121,000 miles on it. The engine spun a rod bearing so the crankshaft and 1 rod are damaged. The block, cylinderheads, etc. appear to be reusable. This is a complete engine with all manifolds, sensors, injection components, flywheel/flexplate, etc.
