Just accidentally ran across this pic of a '67 GTO big tire Super Stocker.
It is indeed the same car raced by Jay Cason, out on the West coast. Perm number 769.
Have never seen another. No, it wasn't quick. But, it ran quick enuff to go rounds, if no heads-up runs were encountered. Mostly, it was just a very rare car to see in the SS ranks.
