LT1 6.2L Engine Specs: Performance, Bore & Stroke, Cylinder Heads, Cam Specs & More

This is an engine specification guide for General Motors’ fifth-generation LT1 engine that launched in 2014.

GM has built three engines designated as the LT1:

• 1970-72 – Gen. I, 5.7L, small block (technically, the first-gen. was written as “LT-1”)
• 1991-97 – Gen. II, 5.7L, small block
• 2014-present – Gen. V, 6.2L, small block

The new LT1 is the Gen. 5, 6.2L, small block engine used in Chevrolet performance cars. It was introduced in the 2014 C7 Chevy Corvette.

LT1 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. However, the LT1 is not Flex Fuel capable (E85).

An LT1 6.2L crate engine is now available.

It is also worth noting that some Corvette versions of the LT1 came with a dry sump oiling system.

The information listed here is for a stock engine.
