SUPERCHARGED POWER MEETS HIGH-TECH EFFICIENCY IN A PACKAGE BRED FOR THE MOST CAPABLE CORVETTE EVER

Straight from the 2015 Corvette Z06—the most powerful production car Chevrolet has ever made—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, 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 650 horsepower and 650 lb-ft of torque.

Our LT4 crate engine is offered with a wet-sump (P/N 19332621) or dry-sump (P/N 19332702) oiling system. A controller specially designed for retro-fit application using an automatic transmission is available.
