Plastic automotive engine
Version one was based on Ford's 2.3-liter Pinto engine and weighed (vs. for its cast iron counterpart). It was designed to produce at 9200 rpm. It was composed of metal cylinder sleeves, metal combustion chamber tops, metal piston crowns, bearings, valves and seats, and a stock 2.3L Pinto crankshaft. Nearly everything else in the engine, including the block, rods and piston skirts, were made of glass reinforced Polyamide-imide thermoplastic resins manufactured at the time by Amoco Chemicals Co. The engine was never installed in a vehicle.
Pangra
The Pangra was based on the Ford Pinto, a car which came about as a result of the 1970s oil crisis and the subsequent move away from big American muscle cars. Jack Stratton, the Pangra's creator, wanted to build a fast, compact car that could compete with cars such as the Porsche 914 and Datsun 240Z. Stratton developed the car with Huntington Ford and the cars were all sold through the dealership. All Pangras were based on the 2-door sedan body style of the Pinto, although there was a one-off Pangra based on the 2-door station wagon. The Pangra appeared on the cover of the January, 1973 issue of "Motor Trend".
