Description
The ultimate engine for your project car
The LT4 supercharged 6.2L V-8 is the latest high-tech small-block crate engine from Chevrolet Performance.
The perfect balance of performance and efficiency, the LT4 leverages the technologies introduced on the 2014 Corvette Stingray’s LT1 Gen-V small-block, including Direct Injection and continuously Variable Valve Timing, while advancing the supercharging technologies established with the previous-generation Corvette ZR1’s LS9 engine. The result is a surprisingly efficient engine capable of producing 640 horsepower and 630 lb-ft of torque.
