I have a 2001 5.3 that was knocking real bad. Think it spun a rod bearing. If you need any parts just hit me up. It is complete from the valve covers to the oil pan. I even have the coil packs and intake. Intake has a dbc throttle body on it. Also the block is busted so it is no good unless someone needs a mock up block or something. I will have pics up tonight after work. Not gonna list all the parts and prices just shoot me an offer of your interested in something and I'm sure we can work out a deal
