72 demon 340 number matching drevetrain

The best advice I've heard here is for you to store it INDOORS and in a SAFE place and drive a beater. You won't regret that. Right now is a poor time to sell a car like that, especially if you bought it even two years ago. The economy sucks right now and even if people have the $$ they won;t give it to you for that car. Wait a few years, I'll bet the market will return for these things and people will be willing to spend the money on that car.
It's a neat Demon 340! You'll have a hell of a time finding another one down the road.
