I got this motor from a friend probably 20 years ago. He said they pulled it out of a late 70s pickup. Doubt it was original to the truck, but it was neat so I held on to it. It has a four speed and a chrome oil pan. Don't know much else other than it still turned over last time I looked at it. I know it's an L18 but that's it. What do I have here? Are they worth anything? Thanks
