Some good info so far, but nobody has mentioned the "Red Brick", aka "Tim's Valiant". Tim Werner took what Ehrenberg did with the Green Brick (69 Valiant, btw) as inspiration and went a step further.
I had the privilege of owning it for two years. I sold it last fall because it was just a bit too "race" for me. It handles like it is on rails. Stiff ride, but not as bad as you would think for a race car.
To find info on this car, Google "tim werner valiant".
Also, check out the Corners Are Best forum on Moparts.com. That's where most of the diehard Mopar corner carvers hang out.
