1968 '340' Barracuda vs 1968 '383' Road Runner

Chip,

You must remember,

The 1968 Road Runner was 'heavily marketed' as a 'Street Musclecar', while
the 1968 Barracuda 340-S had minimal marketing.

Plymouth released the 68' Road Runner on September 12, 1967 - and that
car had more advanced 'magazine advertisements'.
