This car was started out in 1967 when Kas Kastner hired Pete Brock to design and build a new car on the Triumph TR 4A chassis using the 2.5 Liter6 cylinder engine.
The budget was a paltry $25,000.00 including building the car and entering it into the 1968 Sebring 12 hour race. The goal was to get Triumph to take interest and maybe produce a production version.

The car made it to the '68Sebring race but failed to finish.

In the Triumph only race at Sonoma this car just ran away from the field.
