I have to agree about 1963-67 mid-year Corvettes being terribly un-aerodynamic regardless of how "swoopy" they look. As much as I think that they are the most beautiful car the General ever released, stand to the side of one someday and check out the side profile of that near-vertical windshield and a front nose that pushes as much air under the car as over it. I've seen reference to that 7-second reduction time before and it makes me wonder if some automotive writer mis-quoted Zora and meant to say 7 tenths, because that would actually be believable especially if you go by that basic rule of thumb that says a tenth is a car length at the top end. It's not to hard to imagine a 7 car length/7 tenths difference between two cars but think about how big the gap is between two roundy-round cars that finish 7 seconds apart! That's a big gap!
