The focus of any car build is the engine, but with this ’55 Chevy even more care was taken to ensure that this first ever E-ROD installation showcased the powertrain. The team made certain to not hide the wiring and emissions control pieces just to illustrate how these parts work with the base engine. The LS3 fit perfectly where once an in-line 6-cylinder was
One part of the installation of any E-ROD engine that will require some fabrication work is the air inlet. Detailed GM instructions (included with the package) describe where the MAP sensor needs to be located, as well as air filter positioning for optimal power and efficiency. The GM build team artfully fabricated a ’55 air filter canister to accept the
conical airfilter—blending the 50-year old intake with a brand new Camaro-spec LS3!
Backing up the E-ROD LS3 is GMPP’s latest severe-duty transmission, the SuperMatic 4L70-E (P/N 19244043) with the corresponding controller and harness. The driveshaft is a custom aluminum unit. Copeland’s team finished off the powertrain with a GM 7.5-inch S-10 rear
axle running 4.10:1 gearing in an Eaton Limited Slip.
How does a car that features an emissions-compliant engine perform? The LS3 makes big-time power with a rating of 430 horsepower and 424lb.-ft. of torque. And, the E-ROD ’55 weighs less than a new Camaro while offering a lot more rear gear. Add that all up, and the E-ROD ’55 Chevy is a
mid-12-second car in the quarter mile. Yes, your hot rod can have massive power while still remaining environmentally conscious.
E-ROD Engine Details
E-ROD is so much more than just one engine. While the LS3 will bethe first engine that gets the “E-ROD” treatment from GMPP, many more will follow. You can watch for a very affordable 5.3L
variant early in ’10 and even the LS7 (505 horsepower) and supercharged LSA (550 horsepower!) will be included in the portfolio. After that, only the
GMPP engineers know for sure which engines will go E-ROD!
GM Performance Parts’ groundbreaking, new E-ROD crate engine system packages an emissions-compliant combination of parts, starting with the same, powerful LS3 engine that’s found in the Camaro SS and Corvette.

E-ROD Package – LS3 Automatic
This powerful 430-horsepower Corvette engine is the foundation for the NEW, Emissions-Compliant E-ROD package, as described on page 5. The E-ROD configuration includes a custom engine fuel calibration that has been validated with an automatic transmission, as well as the specified exhaust manifolds and catalytic converters. It has been approved as emissions-compliant,
19244805 or 19257230
when installed as a complete, unmodified system. The E-ROD System is intended for use in new performance vehicle builds to meet emissions requirements, as well as to retro-fit past models that may not be deemed
compliant with registration requirements. Check your state registration requirements before installing any non-approved powertrain components..
