Description

 

The LY6 engine is a 6.0L Gen. 4 small block engine used in GM trucks and SUVs between 2007 and 2010. For marketing purposes, it was also known as the Vortec 6000. The engine specs and information listed here is for a stock LY6 engine.

Compression Ratio 9.6:1
Horsepower Rating 364 hp
Torque Rating 383 ft.-lbs.

 

Since LS and Vortec engines are so common, they’ve become the go-to performance and swap engines of the modern era. Upgrades to the motor can take it well beyond these numbers. Camshaft, intake, headers and exhaust can work serious magic once tuned. These motors are capable of making a lot of horsepower, and respond well to upgrades like turbos, superchargers, high-flow cylinder heads, intake systems, cams, and nitrous oxide.

This is a stock pull out, which may have some accessories, stock intake, stock manifolds, etc.
