1964 - THE NEXT LINK

Quick! When did Chrysler build its first K-car?
Wrong! It was 1964 and the Chrysler 300K was indeed, a beautiful car, even though it was clear the letter-series was no longer a priority at Chrysler. Still no slouch at 360 horsepower, the 413 RB-engine was equipped with a single 4-barrel carburetor for the first time in Letter Series history. Was the end of an era in sight?

Dodge entered its 50th year of production with all-new styling and an ever-growing reputation as a performance car to be reckoned with - a concept that sold cars of every configuration in the 60s. Model lines continued unchanged with the compact Dart receiving an all-new 180 horsepower, 273 cubic-inch LA-family V8 engine.

Over at Plymouth, styling refinements and the ever-growing performance reputation of Chrysler products brought buyers into the showrooms in droves. A mid-year offering from Plymouth would set the stage for sales figure increases in the years to come. The all-new Valiant-based Barracuda fastback joined the Plymouth family in the soon-to-be-coined "Pony Car" class. As with the Dart, a Barracuda could be had with either 170 or 225 cubic-inch Slant Six power on the new, lightweight 273 cube V8.

At first glance, 1964 could have appeared to be a "watering-down" year for the Max-Wedge engine just as it was for the 300 cars. Now available in just one version (426 cubic-inch, 425 horsepower, 12.5:1 compression ratio), the Stage III Max-Wedge would see only a 1/2 year production. The competition was beginning to catch up and Max-Wedge was losing its domination in the racing and street wars. And, drag racing was no longer the #1 priority at Chrysler. The company wanted desperately to be a force in NASCAR racing and a secret plan was about to make that possible.

In early February, just in time for the annual Daytona 500, a new "Crate Motor" was released for competition. The 426 cubic-inch Hemi engine (Hemi Charger for Dodge/Super Commando for Plymouth) was put into the hands of factory-backed NASCAR teams, including Richard Petty, and history was written as Petty won the race handily. Within two months, Max-Wedge production was ended and production race cars were now equipped with the new Hemi as a running production change. A 365 horsepower, single 4-barrel 426 "Street" Wedge engine proved a very popular option as did the new A833 4-speed transmission.

NOTE: As much as most of us would like to believe otherwise, the 426 Hemi engine was developed solely for NASCAR stock racing competition. Drag racing versions that came later were, in fact, an after-thought!
