Happy birthday Dutch....
From Wiki....
"He also won the unofficial New York State Modified Championship held at the NYS Fairgrounds (Syracuse, New York) in 1967 and 1968, which were the first two years cars with overhead valve engines were allowed to compete in this race."
Can someone shed some light on the rule preventing overhead valve engines until 1967? Was this rule unique to NYS Fairgrounds? When were overhead valve engines widely accepted? etc?
