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.
Ford Power Stroke engine
The first engine to bear the Power Stroke name, the 7.3L Power Stroke V8 is the Ford version of the Navistar T444E turbo-diesel V8. Introduced in 1994 as the replacement for the 7.3L IDI V8, the Power Stroke/T444E is a completely new engine, with only its bore and stroke dimensions common with its predecessor (resulting in its identical 444 cubic-inch displacement). In line with the IDI diesel, the Power Stroke was offered in one-ton versions of the Ford F-Series/Ford Econoline product ranges.
