Ronnie's reputation as the premier four-speed master was unquestioned, and his driving ability was highly respected by Pro Stock racing peers. Here, he takes on "Akron Arlen" Vanke in Vanke's '68 Barracuda at the NHRA '70 Winternationals. Vanke's car was hastily converted from Super Stock/B class trim to run as a Pro Stocker. Many racers lucky enough to have a '68 Barracuda or Dart made little more than engine modifications and tire changes to compete in the earliest days of Pro Stock (1970-1971). By 1972, the engineered efforts of the Ted Spehar-developed Motown Missile factory test mule, Don Nicholson's 427 SOHC Ford-powered Maverick, and Bill Jenkins' surprising '72 small-block Vega made the S/S-trimmed Darts and Barracudas obsolete. With the '70 'Cuda, Ronnie dominated Pro Stock, going undefeated until losing the Gatornationals to Jenkins' big-block Camaro.
