Big Power LS3 E-Rod Engine System on Sale Now!
Rebel against restrictive emissions laws and build cars with true, roaring power! The E-ROD crate engine package is an unprecedented solution - combining the LS3 engine (known for its incredible horsepower AND efficiency) along with all necessary parts to be legally compliant in even the toughest states. With this powerful option available, car builders can expect muscle at every stoplight...or on their way down a drag strip!
GM Powertrain revolutionized the pushrod platform engine in 2008 with the introduction of their 6.2-liter LS3 V8 into what was then a brand-new Corvette. This powerhouse pumps out an impressive 430 horses and 424 lb.-ft. of torque, but activate its optional dual-mode exhaust system and watch those figures skyrocket up to 436 hp and 428 lb.-ft., respectively! With 376 cubes ready for your command, this small block is no slouch when it comes to muscle cars or potent performance vehicles - bolstered by cylinder heads featuring innovative rectangle ports inspired by their top tier LS7 model engine family member. With 63cc combustion chambers and 2.16-inch intake valves, the LS3 heads provide exceptional airflow for maximum power output at a red line of 6600 rpm. The camshift .551 inch lift produces impressive levels of torque with reduced overlap for unbridled responsiveness under acceleration or load changes; complemented by rocker arms boasting 1:7 ratio to ensure efficient valve actuation in any condition. Further down, an aluminum 6-bolt main block creates serious stability featuring 4.06in bores and 3.62in stroke. Coupled with a nodular iron crankshaft, powdered metal rods, and aluminum pistons (10.7:1 compression ratio) round out a rev-happy short block.
With a high-tech GM foundation, aluminum block, and high-flowing rectangular-port heads, the LS3 is the new standard in the small block world. The LS3 helps power the new Corvette to a top speed of 190 mph. What will it power you to?
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(TM) 4L70-E - P/N 19244043 - four-speed automatic overdrive transmission, along with Chevrolet Performance's SuperMatic(TM) transmission controller P/N 19257634, for LC9 and LS3 systems. The LSA, with higher torque output, should use the SuperMatic(TM) 4L85-E, P/N 19300175, along with the SuperMatic(TM) 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.
