DISCONTINUED - LQ9 6.0L without ECM and Wire Harness - Big displacement equals big torque!

There’s no such thing as too much when it comes to engine displacement. And with 345 horses and 380 lb.-ft. of torque, the 6.0-liter GM Performance LQ9 V-8 makes the most of those cubic inches.

The LQ9 uses the proven LS architecture to provide robust performance in the Cadillac Escalade AWD. It features a sturdy iron block, but like the aluminum-block versions, the LQ9 has a deep-skirt, six-bolt-main block, with structural oil pan and other carefully engineered features to help make it a smooth running and strong engine. A special camshaft and tall intake manifold each are tuned to produce loads of useable torque across the entire rpm range.

GM Performance Parts delivers the LQ9 complete with the intake manifold, throttle body, fuel rail with injectors, balancer, exhaust manifolds, water pump and a flexplate for automatic transmissions. It comes with truck-style oil pan installed. The LQ9 can be fitted to older vehicles, providing modern performance and unquestionable capability. A handy reference guide (see page 276) is available to help install the engine in older cars or trucks with minimal guesswork.
