I have a complete 1986 GN motor and trans with under 40k original miles that was pulled from a wrecked car in 1990 and has been sitting in the shop since then. It even comes with a control panel to run it if you add a battery and fuel. It was ran every couple years and runs like new. Looks like it has aftermarket rockers you can see when the oil filler neck is removed. $2500 plus shipping call or text 253-740-4604 Keith. Im in Washington state
