O-M-R,
I got to ride in a 1968 Cutlass 'Ram Rod' back in the day. The kid who had it, had traded
in his 1966 Olds '4-4-2' in 1968 to get the new 'Ram Rod'.
I had no idea of what it was at the time. It was very quick. And off the line, it felt like
an Elephant had stepped on the rear bumper. The nose came up fast.
Both the Road Runner and 'Ram Rod' were classed in {E/S} back in 1968.
