The car has a 340/727 and 3.91 gears out back. The engine has a mild Comp 262 cam. Suspension was rebuilt using stock parts with a mix of poly and rubber bushings.
I guess I think it should ride/perform like an 80's Camaro or Mustang. It seems pretty far off from that and not in a good way.
And what is it you do with this car? Shows? Cruise-ins? Is what you do so far away that you hate the drive? Sure after almost 30 years you can dump a ton of money in it again to make it ride and handle like a new Challenger, but is that what you really want? If you're not going to part with it maybe you can mothball it for 5 or 10 years then see how you feel.
