A body top speed

While I know most A bodies have the aerodynamics of bricks, I'm curious to see the highest top speeds you guys have managed to wind them out to on "closed courses".My Scamp wont be running until I finish a couple projects that are ahead of it so I'm out.The fastest I've gone was 115 MPH according the the GPS but that was in a 84 nissan 300ZX turbo that was aerodynamically challenged(bought it after a carport collapsed on top of it after 3 feet of snow,so the back is exposed to the elements so it generates alot of drag).
