Caldwell D-7[]

In 1967 Autodynamics launched the Caldwell D7 built to Group 7 rules to enter the 1967 Can-Am season. Sam Posey again was the main driver for the team with Brett Lunger and Ray Caldwell driving selected rounds. The D7 made its debut at Road America where it retired with a broken half shaft. At Mosport Park Posey finished twelfth, the best result of the season.[5] Autodynamics also entered a McLaren Mk. II when the D7 was not ready. With Posey scoring a podium at Stardust International Raceway. The D7 returned in 1968 where it finished fourth at Autódromo Hermanos Rodríguez, the first round of the 1968 United States Road Racing Championship. The following round, at Riverside Raceway, Posey improved to third, scoring the cars only podium finish.[6]

Formula 5000[]

Caldwell had a short lived Formula 5000 project, the D8. Lunger and Posey were the drivers for the one off project. Two chassis were built. Lunger crashed the first chassis during a test, the races were done with a second chassis. In the pro-series Posey scored the best result, a seventh place at Lime Rock Park.[7]

Trans-Am Series[]

Chrysler entered the Trans-Am Series with their two pony car types the Plymouth Barracuda and the Dodge Challenger. The Barracuda's were entered by Dan Gurneys All American Racers. Caldwell was responsible for the chassis. To lighten the chassis the frames were acid dipped. Sam Posey was the full-time driver for the first Dodge Challenger. This chassis was left in the acid to long weakening the roof and structural integrity of the car. The car required multiple chassis repairs between races.[8] The 305ci Dodge V8 engines built by Keith Black proved unreliable causing multiple retirements.[9] Posey scored three podium finishes during the season accumulating all the team's points. During the last two races, at Seattle and Riverside, a second car was entered. Ronnie Bucknum and Tony Adamowicz. The second car retired in both races.

After the 1970 season the pony car market crashed and Chrysler, Ford and Chevrolet canceled their racing programms.[10]

Autodynamics eventually built 3 Challengers and Black provided 12 engines during the season. The cancellation led to a financial crisis for Autodynamics which was forced to reorganize under Chapter 11, Title 11, United States Code.[11]
