That's with Polglas GT tires!



And I'm sure that the '69 Lt-1 Corvettes could turn a low 11 from the factory with the right tires. They are not light cars
I won't dispute you on the big Buick, some of those are awesome. But concerning the LT1 'vette, I don't think they arrived until 1970. And while they were pretty quick, high 12's would be a strong runner in factory trim, even with slicks.
