Mashallah, blessed be God. For those who don't know, this is the best version of the 6-liter iron LS1 6.0 engines. What distinguishes the Escalade version from the Denali version is that it comes with flat pistons, stronger connecting rods, and higher compression. The engine has been completely refurbished by someone who does quality work and spent a lot. High-pressure oil pump, and everything inside has been replaced from static to moving parts, rings, seals, valves, and gaskets. It is currently installed on a 2003 Escalade, and after refurbishment, it has not been driven more than 200 kilometers because the car's plates were lost and I couldn't drive it. Whoever buys the engine can start it and test it, and they have the right to inspect it wherever they want. I guarantee it for you. The engine is considered brand new, zero kilometers. Price: 8000
