I went 132 in my '57 'Vette, on a 1970 interstate. It was also a 327, out to 331, with the usual speed parts.....high rise, holley, fuelie cam, 11 to 1s, balanced, double hump heads, headers, etc., with a muncie and 3:70s.

It was still pulling hard, but I started thinking about the thin rear tires, and backed off. I know...I know...a woosy!
