5.3l V8 L33 from a 2006 Chevy Silverado 1500 Z71. 270k. Replaced the engine with another and rebuilt this one resealed, from the oil pan up. Great engine and many more miles to go the box in the Picture has the rest of the gaskets such as exhaust and intake manifold, water pump thermostat all that. I do have the exhaust manifolds and intake with throttle body. 1500 obo
