This engine was a crate engine used in a automotive training center and not very long ! I'am trying to find out what the exact miles are from teacher about the mileage on motor . It is all there . It runs . It's a 2003 to 2006 LS 5.3 ? Nothing wrong with it ! Very low miles and it is on a test engine stand that comes with it ! All that you see in pics comes with it ! I might have to buy new plug wires for it and sparkplugs because someone snagged them off of it , I'm going to get it running so I can video tape it to add here . Later on stay tuned ..... I'll make a video of it . So you can see it work . I want $8000 firm ! No low ballin here , look up an LS engine to see what they go for before applying here! Thank you and have a great day thanks for looking .... Has key on test engine stand and has gas can and everything else with it . Remember I'm tryin to find out exact miles still ! This engine is still connected to test engine stand , also look up how much test engine stands cost so you know !.
