By far the best thing EVER from the General!
Grew up with an uncle that had 'Vair powered sand rail. Regularly ate up VW powered rails at Glamis and Pismo in the early '70's.
My brother and my uncle both had 'Vairs and I've probably ridden in flat six Chevs a half million miles.
A few years ago, I built a 3 Litre Corvair motor for my Manx. Kind'a funny how much Chev flat six stuff there is still out there.
