The engine and transmission are out of a 1991 G20 van both were professionally rebuilt and only have about 15000 miles on them. They are currently in a 1979 G10 Van so you can drive the parts away and have a lot extra as well. This will work for any G/K/C body Chevy project from the 1970s to 1995. All engine accessories also only have 15000 miles as well. This is a heck of deal if you’re trying to upgrade or get a roller running.
