In addition to the E-ROD system, the builder will need to source additional components to complete the assembly and get the vehicle running. They include:
– Fuel tank
– Fuel lines (re-circulating or returnless)
– Fuel pump
– 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

Each E-ROD engine requires a front-end accessory drive system suitable to 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. They include part numbers 19155066 and 19155067.

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.

This part replaces old P/N 19257234 and P/N 19369332 and P/N 194370415.

E-Rod Systems Have It All

Rated at a strong 430 hp, the original Chevrolet Performance E-ROD crate engine delivers big power with California emissions compliance for countless pre-1995 cars, trucks and SUVs. Along with great power, its aluminum block and heads, and composite intake manifold, make it a lightweight performer, too, meaning your project vehicle will likely enjoy a better weight balance ? with less weight over the front axle. We recommend the 4L65-E transmission to match with the E-ROD LS3 6.2L, (which is also available as an inclusive Connect & Cruise E-ROD crate powertrain system.)

CARB EO#: D-126-31

This part replaces old P/N 19257234 and P/N 19369332 and P/N 19370415.
