1970 Ford Quarter Horse Mustang
Kar Kraft produced only two Quarter Horse Mustang prototype models for Ford in 1969. It was built to potentially replace the Shelby and Boss 429 Mustangs, but was ultimately discarded. The Quarter Horse was also known as the Composite Mustang, given its combination of 1970 Boss 429 chassis, Shelby-style front-end fiberglass, and Cougar instrument panel. The prototypes were used for the 1971 detective series Dan August and performance tests, respectively. They now reside with private collectors.
This model’s owner, Mason Jones, loved the prototypes so much that he decided to build his own. The entire process took three years, from planning the design, sourcing parts, and working with restoration shops. He started with a 1970 Fastback Mustang and a 427 Single-Overhead Cam engine. It initially produced 1,200 horsepower, but was brought down to 850 horsepower to make it more acceptable as a street car.
Other modifications include:
- Eagle crank with Diamond forged pistons
- Replicated Boss 429 shock towers
- 2×4 steel tube brace inside rocker panels, welded to the ‘69-’70 Shelby roll bar
- Aftermarket ’69-’70 Shelby front end fiberglass and chrome trim from Tony Branda Performance
- Custom-built hood with raised center scoop
- 17×8-inch American Racing wheels and 245/40×17 Pilot Sport tires
- Modified factory cluster instrument panel with white-face AutoMeter gauges
- Flowmaster mufflers
- Viper heavy-duty Tremec T-56 six speed transmission
