A brief study

...but, I *still* like the '63 split-window Stingray design the best.

'63
 

Craig Anacker,a classmate and neighbor had one in Woodland Hills,Calif.
British Racing Green.He maintained it meticulously.It was exquisite.
It's my favorite as well.
There's a photo of its development model in Cal Tech's GALCIT wind tunnel with lamp black smears,driven by the airstream.The flow looked good.
Probably around Cd 0.50 back then.With its small frontal area and small-block power,a nice screamer!

Those lines being upswept on the back half of the rear fender are tell tale signs of a large vortex formation starting above the rear tail lights and being dragged along by the car for possibly several hundred feet at highway speeds.
