LS3 CARB APPROVED 430HP ENGINE
E-ROD LS3 System – CARB EO # D-126-30
Chevrolet Performance leads the industry with E-ROD crate engine systems and supporting components that enable enthusiasts to build a car that complies with the law, satisfies their desire for a cleaner hot rod and doesn’t sacrifice the performance.
All E-ROD crate engine systems – 5.3L, LS3 and LSA – are certified by California Air Resources Board (CARB) and carry Executive Order numbers. This enables enthusiasts to install the engine kit in 1995- and-earlier cars and trucks that predate OBD II on-board emissions diagnostics.
All engine systems are offered in automatic- and manual transmission calibrations and each includes the engine controller and other necessary components, including:
- Exhaust manifolds
- Catalytic converters
- Oxygen sensors and sensor bosses
- Fuel tank evaporative emissions canister
- Mass airflow sensor and sensor boss
- Accelerator pedal (for use with the electronic throttle body)
- Air filter
- Instruction manual
About the E-ROD engine controller – The engine control module included with each E-ROD crate engine system is designed for true stand-alone performance in older vehicles. All that’s needed to get a vehicle running with the engine controller are power and ground sources, a high-pressure fuel pump and an electric cooling fan. Chevrolet Performance recommends a 58-psi (400 kPa) fuel pump for the 5.3L and LS3 engines; and a 65-psi (450 kPa) fuel pump for the LSA.
Chevrolet Performance’s specially calibrated engine controller does not engage a number of features associated with production-model systems, eliminating the possibility off ”trouble codes” being set. It also includes a SES (service engine soon) LED indicator embedded in the fuse box.
The LS3 6.2L is the 430-hp standard engine in the Chevrolet Corvette and is a fantastic combination of high-technology and uncompromising performance. Our LS3 crate engine comes complete, from the Corvette-specific oil pan to the ignition system. It also includes the EFI intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58X reluctor wheel and 14-inch automatic-transmission flexplate.
Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhancing the LS3’s tremendous airflow and broad torque curve.
The Corvette oil pan doesn’t suit all installation applications. Use a vehicle-specific oil pan for original LS-powered vehicle or Chevrolet Performance’s Muscle Car Oil Pan Kit P/N 809-19212593 for older vehicles.
In addition to the E-ROD system, the builder will need to source additional components to complete the assembly and get the vehicle running.
- Fuel tank
- Fuel lines (re-circulating or returnless)
- Fuel pump
- Fuel tank vent line from the tank to the evaporative emissions canister
- Pure line from the canister to the engine purge solenoid
- Air induction system that incorporates the mass airflow sensor
- Exhaust system behind the catalytic converters
Each E-ROD engine requires a front-end accessory drive system suitable for the vehicle. The instruction manual includes recommendations for the accessory drive kit, as well as the transmission, gear ratios and more. Chevrolet Performance offers two configurations of the 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 809-88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.
NOTE: E-ROD systems do not come with a transmission. Chevrolet Performance recommends the Hydra-Matic 4L65-E or 4L85-E – four-speed automatic overdrive transmissions, along with SuperMatic transmission controller P/N 809-19257634 or 809-19257661
