I have a rebuilt 4.2L I 6 from a 02-05 Chevy trailblazer. Rebuild has ~10k miles on it and it was rebuilt by the dealer. I purchased this engine for my envoy when it need a new engine and I didn’t know that it wasn’t compatible with a 08 Envoy due to a difference in cam shaft position sensor only. Had it in and running without the computer….. would run with the computer however. I am asking $1,200 for the engine that also comes with a 2wd transmission with about ~125k on it. I have statements from the dealer to prove. Please contact to with any inquiries @ [email protected]
