I am selling a new 4.8L GM engine. I traded for it to use in a project vehicle. I am realizing I'll never get to it, so I'm selling it. It was bought from a dealer a few years ago and always stored inside. My understanding is it was for an Express van and doesn't have the AFM. It has never been installed has lived on the pallet. Something bumped it at some point and broke the valve cover at the oil fill. Everything else is good on it. Let me know if you have any questions and I'll do my best to answer them.
