 In 1982, in a major expansion of its racing engine parts business, Bill Miller Engineering purchased the old ForgedTrue Piston company. ForgedTrue was started by hot rodding pioneer, Art Sparks, at the end of World War II. Sparks was the inventor of the manufacturing process used to make a forged aluminum piston. When war production ceased in 1945, all of a sudden, Sparks’ friend, aircraft manufacturer Donald Douglas, had a lot of unused forging presses in his aircraft plant at Santa Monica, California. Art Sparks made a deal with Douglas to use those presses to make forged pistons for the Offenhauser, four-cylinder, race engine.

ForgedTrue went on to become a major brand in the premium racing piston field during the '40s, '50s and '60s. Not only did Sparks have his own successful business, but TRW paid him a lucrative royalty to use his forging process in its volume-market, forged pistons which were both used by O.E manufacturers and widely sold in the aftermarket. Art Sparks retired a very wealthy man.

During the 1970s, ForgedTrue Pistons changed hands several times.
