The General Motors Fuel Injection history can not be told just by itself because the GM Fuel Injection timeline parallels that of the Chevrolet Corvette and the Chevrolet V-8:

— The 1953 GM Motorama Corvette Dream-car promised an American sports car to compete with Europe’s best.

— The 1955 Chevrolet V-8 engine promised a powerful engine with unparalleled reliability and durability.

— The GM Fuel Injection system promised unsurpassed engine performance with exceptional fuel economy!

Every step at the Chevrolet Motor Division in the development of the Corvette and the V-8 were in preparation for Fuel Injection and every step in the development of Fuel Injection was for the Corvette V-8.

The General Motors executives responsible for the iconic Chevrolet Corvette, the Chevrolet V-8 and the legendary “Ramjet” Fuel Injection program at Chevrolet Motor Division were Harlow H. Curtice, Harley J. Earl, Edward N. Cole, Harry Barr, Zora Arkus-Duntov and John Dolza.

Without the generous use of the General Motors Media Archives Photo Collection there could be no such book by any author.

It was a great surprise and privilege for the author to read the original GM Photographic Log Books and decipher where Fuel Injection photographs were hidden all these years. Had the original photographer’s assignment and description not been so obscure who knows if they would still be there!

The story the GM Media Archive’s photographs tell of the trials and tribulations necessary to bring such a remarkable and significantly important automotive technology to market, three decades in advance of governmental regulations for fuel economy and exhaust emissions that would mandate it, needs to be told.

Nearly 40 years of engineering and management experience in General Motors and 30 years researching the Rochester Fuel Injection system, provides the author with insight and perspective necessary to tell the GM Fuel Injection story including the interactions between the Corporation, Styling, R&D, Chevrolet Motor, Rochester Products, AC Spark Plug, Packard Electric and Delco-Remy divisions.
