More than 550 supercharged hp with exceptional refinement The Cadillac CTS-V’s 6.2L supercharged LSA engine delivers 556 horsepower with refinement that is rare in the world of high performance. It is smooth, quiet, and well-balanced — all while delivering breathtaking power. A unique aluminum cylinder block casting houses a forged-steel crankshaft and super-tough reciprocating parts, integrated piston-cooling oil jets, and high-flow cylinder heads that support the airflow enabled by a 1.9L, sixth-generation supercharger with four-lobe, high-twist rotors. The advanced rotor design broadens the supercharger’s effective range, enhancing low-rpm torque and high-rpm horsepower. Chevrolet Performance’s LSA 6.2L supercharged crate engine package comes fully dressed, from the top of the charge-cooled supercharger assembly to the ignition system, water pump, balancer, and more. It is a less costly alternative to the LS9 engine and makes a great transplant for any off-road LS-powered vehicle or pre-1976 car or truck. It also comes with conventional wet-sump lubrication system. NOTE: This engine includes an eight-bolt crankshaft flange that may require an adapter for use with some transmissions.

To facilitate a complete E-ROD installation, the builder will need to source additional components to complete the assembly and get the vehicle running, including:
• Fuel tank
• Fuel lines (re-circulating or returnless)
• Fuel pump – 58 psi (400 kPa) for LC9 and LS3 or 65 psi (450 kPa) for LSA
• Fuel tank vent line from the tank to the evaporative emissions canister
• Purge line from the canister to the engine purge solenoid
• Air induction system that incorporates the mass airflow sensor
• Exhaust system behind the catalytic converters.
All E-ROD engines require a front-end accessory drive system suitable to the vehicle. The instruction manual included with each kit offers recommendations for the accessory drive kit, as well as the transmission, gear ratios and more. Chevrolet offers several configurations of accessory drive systems to suit different applications; and each allows the installer to easily delete air conditioning.
Chevrolet Performance recommends the LS1 Engine Installation Guide P/N 88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.
E-ROD systems do not come with a transmission. Chevrolet Performance recommends the SuperMatic™ 4L70-E – P/N 19244043 – four-speed automatic overdrive transmission, along with Chevrolet Performance’s SuperMatic™ transmission controller P/N 19257634, for LC9 and LS3 systems. The LSA, with higher torque output, should use the SuperMatic™ 4L85-E, P/N 19300175, along with the SuperMatic™ transmission controller, P/N 19302410.
*GM automatic transmissions are typically equipped with 40-tooth reluctor wheels for vehicle speed sensor output. GM late-model manual transmissions are typically equipped with a 17-tooth reluctor wheel. The Chevrolet Performance T56 Super Magnum six-speed manual (P/N 19329795) is equipped with a 40-tooth reluctor wheel.
