1967 - OFFICIAL MUSCLE EVERYWHERE

Possibly the biggest news from Chrysler for 1967 was the introduction of the Plymouth Belvedere, GTX and Dodge Coronet R/T, making the corporation's first entry into the street wars with "officially-badged" musclecars. Standard power for the GTX and R/T came from a 375 horsepower version of the new 440 cubic-inch engine known as the "Magnum" at Dodge and the "Super Commando" at Plymouth. Optional for each was the 426 Hemi. The 440 and Hemi were both optional for the second-year Dodge Charger.

Moving down in size we find the Barracuda and the new Dart "GTS" (both with larger, totally-restyled bodies and re-engineered platforms) still available with the 235 horsepower 273. But big-block power was now available in the form of a slightly detuned 280 horsepower version of the 330 horsepower 383 cubic-inch B-engine. Camshaft and exhaust compromises made for the diminished rating.

For serious "off-road" competitors, Chrysler offered the Belvedere II and Coronet 440 Super Stock cousins. Known as the RO and WO cars (for their first two serial number digits) the cars were built without all of the heavy sound deadener and body caulking of a normal production car. Under the hood was a specially-prepared 426 Street Hemi with a massaged intake manifold as just one of its trick pieces.
