How to Engineer a Corvette Small Block Engine

Gary S. Vasilash

The LT1 6.2-liter Small Block V8 developed for the 2014 Corvette Stingray will produce an estimated 450-hp and an estimated 450 lb-ft of torque. This first member of the Gen 5 family of engines is not only powerful—it is estimated that the Stingray with the LT1 will be the fastest standard ‘Vette ever—but it is fuel efficient as well: it is projected that it will get better than the 2013 Corvette’s EPA-estimated 26 mpg highway.

Among the reasons why this can be achieved are direct injection, active fuel management, continuously variable valve timing, and a new combustion chamber design. Some six-million hours of computational analysis were spent on developing the combustion chamber, alone.

What went into the development of this potent powertrain, as well as the new EcoTec3 lineup for the 2014 GM full-size pickups (4.3-liter V6, 5.3-liter V8 and 6.2-liter V8), are among the topics covered in this installation of “Autoline After Hours.”
