I was riding around the test grounds with Jim Bilenda in his Challenger T/A and Jim Walton came screaming by in his petty blue Hemi bird. We were doing about 60 and he went by at about 125.
Later,We were sitting at the bottom of the down hill grade and Jim came down so fast he bottomed the bird out on the blacktop.

We caravaned up with several cars ( no trailers ), one was a black 1972/73 charger with a home made nose cone and rear wing made of balsa wood. at hiway speeds the wing would sway back and forth 6 inches or more.

I'll have to dig my pictures out this weekend.

That was the 1st year I met the current owner of the Cuda I'm restoring now.
