I think from memory that during one of the 427SC Cobra banner years when they carried all before them Don & that other special chevy driver Jim Hall were the only guys to win their SCCA class.
A lot of people put down SCCA racing, and in the 70's it might pale beside IMSA and Trans Am but in the 60's it was KING.
There is an established group of Vette people who don't want Corvette racing history to progress past Sthn Calif and the solid axle fuelies, its a type of politics.
The L-88 guys (Don was one of the first two running proto type L-88s, Penske was the other in 66 ))don't get enough
credit.

Also think that the popularity of the Yenko Camaro with the public, hurts his claim. Corvette guys may just be a little envious at how Yenko prices have outstripped the L-88s.
Personally anyone who can drive a Vette to victory over a 427 Cobra has my vote.
Just an opinion
