About the LQ9 Vortec Engine

The LQ9 was GM’s high-output 6.0L iron-block V8, used in the Escalade, Silverado SS and Sierra Denali in the early 2000s. It has flat-top pistons and higher compression than the more common LQ4, which gives it extra power and makes it a favourite for turbocharged LS builds. The iron block is extremely strong and can support high boost with the right parts.

Getting the LQ9 Vortec engine with its computer and harness saves you from sourcing matching electronics, which is often the hardest part of an LS swap.

Before You Buy

• Confirm the computer can be tuned for your transmission and VATS removed.
• Choose an oil pan and accessory drive for your chassis.
• Plan a fuel system that supports the engine and any future boost.

Installation Tips

Inspect the harness for damaged connectors, replace the rear main seal and water pump if needed, and have the computer tuned for your setup.
