I had a stock 1968 Camaro. It moved pretty good.
My mom had a 1968 Red Camaro 327 with two-speed slush box that was a rusted out hulk by the time I turned 16 and got to drive it in 1975.
It scored cool points in the high school parking lot, but it was the slowest thing on Gratiot Avenue. (I grew up in St. Clair Shores, MI.)
