Will different color combo de-value my '72 Demon 340?

Tor Red is a beautiful color. Not sure why you would change it. People pay big bucks for clones. I don't see a color change making much difference on a real 340 car. If you got a buyer they can always change it back seeing how it isn't the origional paint anyhow. 450+ BHP DYNO'D...be sure and tie the subframe. 4:30's are great as long as you don't get on the frwy much. I had a set in a 383 GTS Dart and loved them. Great for burnin a lot of rubber. 3k rpm at 50mph. 3:55's are better if you like cruising. I'd like to try out the new 3:73's I've seen advertised in the Mopar mags.
