    The Race-Ready LS Built For The Strip!

    Free Shipping!

    The all-new Chevrolet Performance DR525 drag racing crate engine, designed as the spec engine for National Muscle Car Association's new LS Stock racing class in the LSX Showdown Challenge Series. This 6.2L (376 cubic inches) naturally aspirated engine is rated at 525 horsepower and features several tamper-proof bolts to ensure class compliance. Chevrolet Performance's custom-calibrated E67-type engine control system (p/n 809-19329003, sold separately) must be used with the DR525 in the LS Stock class. It features a tamper-proof engine control unit.

    On the inside, the DR525 crate engine is built with components designed to meet the high standards of competitive racing. The 376 cubic inch aluminum block is packed with a sturdy reciprocating assembly that combines with LS3-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.525-inch of lift on the 2.16-inch intake valves and 0.525-inch lift on the 1.59-inch exhaust valves, enhancing the LS3's tremendous airflow and broad torque curve.

    LS Stock overview
    NMCA's LS Stock class in the LSX Showdown Challenge Series is a naturally aspirated heads-up class designed for 1955-later vehicles and is designed as a low-cost, entry level heads-up class. All entries must compete on accepted suspensions and at the same base weight of 3,300 pounds. The class is an all-run, heads-up field using a .400 Pro Tree start. Additionally, all entries are required to read and sign a racer's contract to prevent class participants from tampering with and/or altering the factory-sealed Chevrolet Performance DR525 crate engine and requisite engine control system.
