It's doubt that a 383 2v low compression wagon would have a sure grip. Some of the c bodies did come with them, but most had a 4v and/or duals to back that up. You never know what the owner may have done though.
I will say that there are all kinds of parts on that car you could get for future jobs. I myself like period correct nuts and bolts, any harness you can snatch up, clips, the a/c bracket and pulley system, The brake system, any power window seats and window motor stuff, fm radio and or speaker wires, that's if you have the time and space. Even the engine and trans would be a good choice.
