E-ROD Package - LS3 Automatic

E-ROD crate engine package—an unprecedented, emissions compliant powertrain that includes an LS3 crate engine and other necessary parts to be 50-state emissions compliant. With the LS3 engine and its stunning combination of horsepower and efficiency, a car builder can expect great performance at the drag strip or just cruising around town.

There are several states (as well as foreign countries) that require emissions compliance for specialty constructed vehicles. This has made it increasingly difficult for enthusiasts to build true high-performance cars and stay in the good graces of the law. E-ROD engines are an answer to these political pressures. GMPP worked closely with the influential California Air Resources Board (CARB) and secured approval that makes E-ROD-equipped vehicles compliant in California and other areas that mirror CARB's recommendations and emissions standards. GMPP is the pioneer for this new era in hot rodding, as no other O.E.M. or aftermarket manufacturer offers a comparable, CARB- approved system.

Starting with the '08 Corvette, the world was first introduced to GM's latest small block V8 creation the 6.2-liter LS3. A continuation of the industry leading V8 engines from GM Powertrain, the LS3 kicks out 430 horsepower and 424 lb.-ft. of torque. (In the Corvette, those numbers go to 436 hp and 428 lb.-ft. of torque with the optional dual mode exhaust system.) It's a brute of a small block with 376 ready cubes at your beckon call.

The LS series of engines from GM Powertrain have broken new ground for efficiency and performance from a pushrod platform engine. The LS3 continues the engineering breakthroughs with revised cylinder heads featuring rectangle ports borrowed from the vaunted LS7. The heads feature 63 cc combustion chambers, 2.16-inch intake valves, and 1.59-inch exhaust valves. The camshaft features an aggressive .551-inches of lift on the intake side with less overlap (than the LS2) for even greater airflow and power. Rocker arms with a 1.7:1 ratio sit on top of the heads.

In the bottom end, the aluminum 6-bolts/main block features 4.06-inch bores and 3.62-inch stroke. A nodular iron crankshaft, powdered metal rods, and aluminum pistons (10.7:1 compression ratio) round out a rev-happy short block. Red line for the LS3 comes at 6600 rpm, and you will get there very quickly.
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?

The hot new small-block V-8 in the GM lineup is the hyper -aggressive LS3. It offers a high-revving 376-cid combination that represents generations of small-block V-8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!

The LS376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-revving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.

The GM Performance Parts engineers picked the LS Hot Cam (P/N 88958733) to take the LS3 to the next level. This cam specs out with .525" intake and exhaust valve lift. Duration (@ .050") is 219˚ª intake and 228˚ª exhaust, which allows for a dramatic increase in power. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it.

The LS3 gets a big cam and carbureted intake manifold for an additional 85 horsepower!

You know that the LS3 is the hot new small-block V-8 in the GM arsenal, but you still want more. We proudly offer you the LS376/515, an upgraded LS3 that is equipped with an aggressive camshaft and GM Performance Part’s exclusive carbureted intake manifold. Two simple upgrades that add up to 515 horsepower—an 85 horsepower bump over the stock LS3.

The LS3 comes fully equipped with components that only a few years ago would have been the exclusive property of race engines. The block is a rock-solid 6-bolt foundation that holds together the 4.06" bore by 3.62" stroke rotating assembly. The LS3 heads are high-flowing rectangular port aluminum castings. What separates the LS376/515 from the base LS3 is the addition of a GM Performance Parts high performance camshaft and a carbureted intake manifold.

To match the high flow rate of the LS3 cylinder heads, our GM Performance Parts engineers installed the “ASA Hot Cam” (P/N 12480110). This is a hydraulic roller camshaft that offers up .525" intake and exhaust valve lift numbers and duration @ .050" of 226˚ª intake and 236˚ª exhaust.

The GM Performance Part engineers coupled that aggressive camshaft and high flowing cylinder head design with our new carbureted intake manifold specific for the L92/LS3 cylinder heads (P/N 25534401). The manifold offers a dramatic increase in horsepower and a simplified installation.
