LT4 6.2L Engine Specs: Performance, Bore & Stroke, Cylinder Heads, Cam Specs & More

This is an engine specification guide for General Motors’ fifth-generation supercharged LT4 engine that launched in 2015.

GM has built two different engines designated as the LT4:

• 1996–1997 LT4 – Gen II, 5.7L, small block
• 2015–Present LT4 – Gen V, 6.2L, supercharged small block

The high-performance 6.2L, supercharged Gen 5 LT4 debuted in the 2015 Chevy Corvette Z06.

LT4 6.2L engines are all aluminum and use Active Fuel Management (AFM) and Variable Valve Timing (VVT). The engines also use direct fuel injection technology, which shoots fuel directly into the combustion chamber instead of the intake runner.

The LT4 is not Flex Fuel-capable (E85).

The LT4 makes 195 horsepower and 195 ft.-lbs. of torque more than its naturally aspirated cousin, the LT1. To accomplish this, the LT4 uses:

• A compact, 1.7L blower
• A stronger crank, rods, and pistons
• Rotocast aluminum heads

Some versions of the LT4 came with a dry sump oiling system.

An LT4 6.2L crate engine is now available.

The information listed below is for a stock engine.
