- Chevrolet Performance LT4 Supercharged 6.2L Crate Engine -V8/650HP
The all-new LT4 supercharged 6.2L V8 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. The LT4 is based on the same architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction.
