up for sale is a 2006 5.3L vortec engine with 20,000 original mile came out of a silverado 1500. I have the ecu and a standalone wiring harness from P.S.I systems. Perfect fit for a c-10 project the engine also has a ls1 hot cam from comp, chrome shorty headers and a throttle body spacer. The engine has been completely painted in high heat paint gloss black and victory red. I'm looking to get 2,500$ for the whole setup but I would be willing to trade for a 350 or 383 small block that is in GREAT shape no junk please don't waste my time SERIOUS buyers only !
