19416892 - Chevy Performance EROD LSA 6.2L 556 HP Supercharged Engine A/T Package

E-ROD crate engine package—an unprecedented, emissions compliant powertrain that includes an LSA crate engine and other necessary parts to be 50-state emissions compliant. With the LSA engine and its stunning combination of horsepower and efficiency, a car builder can expect great performance at the drag strip or just cruising around town.
There are several states (as well as foreign countries) that require emissions compliance for specialty constructed vehicles. This has made it increasingly difficult for enthusiasts to build true high-performance cars and stay in the good graces of the law. E-ROD engines are an answer to these political pressures. GMPP worked closely with the influential California Air Resources Board (CARB) and secured approval that makes E-ROD-equipped vehicles compliant in California and other areas that mirror CARB's recommendations and emissions standards. GMPP is the pioneer for this new era in hot rodding, as no other O.E.M. or aftermarket manufacturer offers a comparable, CARB- approved system.

The new 2009-2013 Cadillac CTS-V ups its performance with an all new 6.2L supercharged LSA engine that delivers 556 HP making it second only to the Corvettes LS9 supercharged engine as the most powerful production LS crate engine offered by GM Performance Parts. It is based on the same foundation as the LS9, but with a slightly smaller supercharger and a few other unique components designed to deliver Cadillac's signature quietness and refinement.

But just because the LSA doesn't have the same peak power numbers of the LS9 engine doesn't mean it comes up short in any important measurement. The unique aluminum cylinder block casting houses a forged steel crankshaft and super tough reciprocating parts, integrated piston cooling jets, high flow cylinder heads and a relatively mild camshaft with .492" lift on both intake and exhaust sides.

The forced induction of the 1.9L sixth generation supercharger makes up for the comparative lack of valve lift by packing the combustion chamber full of air and fuel. This gives the LSA 556 horsepower and 551 Ft. Lbs of torque, along with excellent idle quality and "right now" throttle response. And unlike the LS9, the LSA comes with a conventional wet sump lubrication system.
