Crate Engines

LS3 - 525HP With Chevrolet Performance’s aggressive ASA camshaft – developed for the high-rpm world of circle-track racing – installed in the LS3 6.2L engine, it comes alive with 525 uncompromising horsepower. That makes it the most powerful naturally aspirated 6.2L

Engine Controller Kit The engine control module is the is the brain of your Gen III/IV LS- or Gen V LT-powered project vehicle and Chevrolet Performance is your source for controllers designed for easy, “plug-and-play” installation and, in most applications, no need for third-party tuning adjustments. Unlike controllers from regular-production vehicles, which may or may not come with a used engine, Chevrolet Performance controllers are uniquely calibrated for installation in older vehicles. That means many features required for late-model production vehicles are “turned off,” because they’re not required in older cars and trucks. That prevents the unnecessary triggering of diagnostic trouble codes that could possibly affect performance or require additional calibration adjustments. Our inclusive kits deliver all the components required to plug into the engine and get it running – from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors and even a throttle pedal assembly for engines equipped with an electronic throttle body. The kits also include detailed instructions to help you do it right the first time, even if you have no experience. Most kits include: • Two oxygen sensors • Two oxygen sensor mounting bosses (for installation in the exhaust system) • A mass airflow meter • A mass airflow meter mounting boss (for installation in the air intake system) • A throttle pedal assembly (for use with the electronically operated throttle) • A specific oil pressure sensor that is compatible with the harness (when needed) • A complete wiring harness with fuse box and necessary cam sensor and MAP sensor jumpers

street engine in our portfolio – and one that has an edge to it.You’ll notice it in the idle quality and you’ll feel it when the revs quickly climb.

The ASA camshaft is a hydraulic roller with .525-inch lift on both sides, along with 226 degrees duration on the intake side and 236 degrees on the exhaust side. Coupled with a tight, 110-degree lobe separation angle, it helps the engine deliver excellent throttle response and breathe exceptionally well at high rpm. And for durability, we complement the cam with higher-rate valve springs. You’ll need tuning to make the most of the engine in a late-model GM vehicle. If you plan to use the engine in a vintage car, you’ll need controller kit P/N 19354332, which includes the throttle pedal to match its electronically controlled throttle body.
