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

In my opinion, the Road Runner was a great marketing car.
A low cost Muscle car with good potential.
It worked well for Plymouth from a profit standpoint.
I would think the profit margin was better on the RR than the Barracuda.
Maybe someone could chime in about that.
This could be the reason for low sales of the Barracuda, all the marketing seemed geared toward the RR.
That being said, I wouldn't be ashamed to own a Road Runner at all.
