Fantastic little cars. I had a 280z with the bored out L28 but also fuel injection. Not a difficult car to work on, mine was barely running when I got it. Did my own valve adjustments and adjusted the throttle as well as oil/cap, wires and plugs, and I got it to run like a champ. Unfortunately, these cars RUST! Mine wasn't beyond fixing but I had no where near the budget to do it properly so I sold it. I still kick myself in the head because I had a perfect running drive train, and someone on Long Island was selling a perfect 240 shell he redid with new brakes and coil overs, and interior, just missing engine/trans. I could've bought it and swapped mine in then just sold my 280 shell but my family at the time talked me out of it. Now they even say it was a stupid idea not to I think I want another one day, maybe with a nice powerful swap, but I love them. Look out for rust, the best of examples can have it, and go from there. Make sure the body is straight and I'd offer maybe $2000-3000 max if the body is decent and its not running.
