Chevrolet is showing off some of its impressive new performance tech at 2015 SEMA Show in Las Vegas. One of the most interesting vehicles at the show is this classic 1970 Camaro RS concept vehicle. What's special about this classic Camaro is that it has a supercharged 6.2 liter LT4 crate engine under the hood that produces 650 hp and 650 lb-ft of torque. The LT4 represents somewhat of a milestone for General Motors as it's the most powerful engine to ever be placed in one of the manufacturer's production vehicles.

The LT4 is based on the design of the Gen V small block used in the LT1 engine that powers the 2016 Camaro SS and Corvette Stingray. However, the LT4 supports a higher output and higher level of cylinder pressure created by forced induction.

Regarding the LT4 engine, Jim Campbell, U.S. vice president of Chevrolet Performance Vehicles and Motorsports stated that "... the LT4 represents a new threshold in technologically advanced, production-based choices for builder. Whether it's in a classic Camaro, like this resto-mod concept, or a vintage truck or street rod, the possibilities are almost endless – and that's exactly how we continue to fuel the dreams of enthusiasts."
