The First 1967 383 A-Body, 'Barracuda or Mr. Norms's Dart'
Gino,
Car and Driver {December 1966}
As noted, Car & Driver stated that the 383/280 HP in the 1967 Barracuda 383 was 'purposely' rated at a low Horsepower
to get the 1967 Barracuda classed in a lower NHRA Class.
The skeptics were not so sure that the NHRA would accept a 280 Horsepower Rating, when the 'same' 383 4-Barrel was
rated at 325 HP in the Mopar B-Body cars.
Car & Driver could not find a {45 Horsepower} difference, and doubted whether the 'restrictive exhaust' could effect
the 383 that much.
