I am offering a GM engine from 2000 to 2006, 5.3L, factory original. I removed it from my car, it has no issues. For sale to anyone looking for a clean engine. Selling without installation. To save time, folks, the engine is factory original, never opened, no overheating, no smoke. In Arabic: cleaner than what you'll find in a scrapyard and cheaper too. They sell them in scrapyards for 3500 and you don't get a guarantee. Whoever wants something for personal use and clean, this is it. The engine fits Yukon, Tahoe, Suburban, Sierra, and Silverado.
