For those who don't know, the NASCAR Hall of Fame is being built in Charlotte and will be opening May 11, 2010.
http://www.nascarhall.com/The perfect tie in for the Charlotte area to see both of these in a trip.
My personal thought is that it will be the tallest, fastest and/or longest roller coaster in the South. Possibly all 3.
I think all that is needed to do this would be:
Speed: 86 mph
Height: 256 feet
Length: 5313 feet
It wouldn't be out of the question to have all 3.
Tie it in with an Earnhardt theme and call it the Intimidator and watch the lines form.
