I just sold my absolutely atrocious 1990 na chassis with no drivetrain whatsoever, no seats, and no front bumper for 800,(Not to mention the fast and furious incredible hulk paint job that some idiot did to it.) If it's in pretty good shape and you have everything but the engine, I'd start but asking for like 1600 to 2000 for it. Especially out in CA, there's a pretty big market for them. Just advertise out the ass for it. I suggest just buying a new engine with lower miles. You can get an NA engine with pretty low miles fairly cheap instead of rebuilding one. Good luck with the sale and/or the new engine.
