About the LS3 580HP Engine

The LS3 is GM’s 6.2L aluminum small-block with large rectangle-port heads. It is already strong in stock form, and with the right camshaft, valve springs and induction it responds very well to upgrades. The FAST LSX intake is a well-known high-flow composite manifold that helps the engine breathe at higher rpm, supporting the power level of this LS3 580HP engine.

Choosing a built engine like this saves you the time and cost of assembling and tuning parts yourself. It is a strong fit for Camaros, Chevelles, C10 trucks and other platforms that already have LS swap support.

Supporting Parts to Plan For

• A fuel system sized for the power level, including injectors and pump.
• An ECU or standalone tune to match the cam and intake.
• A transmission, driveshaft and rear axle rated for the extra torque.

Installation Tips

Prime the oil system, verify fuel pressure and use a qualified tuner for the first start and break-in. Check valve spring pressures and plug condition after the first runs.
