Chevrolet Performance has released its latest factory-engineered LS high-performance sealed race engine - the DR525. It blends the racing-derived ASA camshaft with the LS3 6.2L production engine to create the most powerful production-based crate engine in Chevrolet Performance's portfolio - delivering 525 horsepower at 6,300 rpm and 489 lb.-ft. at 4,400 rpm.
Using the Chevrolet SS LS3 production engine as the foundation for the LS376/525 helped keep the retail price lower, while the ASA camshaft is a proven, power-building component that has been successful in the high-rpm world of circle track racing.
The ASA camshaft is a hydraulic roller with .525-inch lift on both the intake and exhaust 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 breath exceptionally well at high rpm.
As delivered, the DR525 includes the intake manifold, with the injectors, fuel rail and throttle body already installed, along with the water pump and ignition system.
Chevrolet Performance installs Tamper Proof Bolts in the DR525 for affordable heads-up drag racing classes. These Tamper Proof Bolts are located (1) oil Pan, (1) front timing cover and (2) each side of intake manifold.
