The LT1 V8 powerplant found under the hood of Chevrolet C7 Corvette Stingray produces a healthy 455-460 horsepower and an equal amount in lb-ft of torque. For some, that’s plenty, but others are left thirsty for more. While they have the option to go all out with a Lingenfelter Performance Engineering supercharged V8 crate engine rated at 720 horsepower, the LT1 Heads and Cam package is a great alternative to the performance of a blower. In fact, LPE has designed cam packages that are rated as high as 630 horsepower.
The 630 horsepower cam package eliminates the cylinder deactivation and variable valve timing systems of the LT1, but the systems aren’t lost in the 550 horsepower heads and cam package. In any case, LPE has been able to figure out ways to improve the LT1, despite it’s sophisticated and efficient design.
“Taken all together, there is a lot to wrap your arms around with the new LT engines,” says Mike Copeland, LPE’s vice president of operations. “It’s still a familiar cam-in-block V-8, but the technologies employed to optimize performance and efficiency in production form mean the traditional methods of increasing horsepower require different approaches to generate a result that doesn’t sacrifice drivability or overall performance for a comparatively minor maximum power gain.”
