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

i only see a little over 5K barracudas with a performance engine, compared to over 46K RR's. Roadrunner was Chrysler's first true muscle car not available with any low performance engine until the 70's.

While the 1968 Road Runner was 'the most popular' Mopar Street Musclecar.

The 1967 GTX was the 'first true' Mopar Street Musclecar
