For sale: HD2500 engine, 6.0 iron LY6. The engine was worked on by a performance workshop. It has a Texas Speed torque cam with Motion Single springs. It has been driven less than 20,000 km after the rebuild. The engine is very clean with high torque. I guarantee it for starting only. It is currently installed on the car and running. Stock crank, stock pistons, Denali oil pump. I just came back from the south with it, but fate willed it. It fits all GMC and Chevrolet models from 2013 and below: Yukon, Suburban, Tahoe, Denali, Sierra, Silverado, Caprice, and for modified/custom builds. The price is 10,000 for the intake manifold, throttle body, and injectors only. Note that its throttle body is for a Caprice and the intake manifold is for an HD. The attached video is of the same engine. The picture is for illustration only. For other parts: Long headers, original Magnaflow muffler (complete exhaust system), alternator, and other parts are priced separately. They fit a Trailblazer SS.
