Chev LS 6.2L 376cu. DR525 long block crate engine
Chevrolet Performance's DR525 sealed drag racing crate helps enable exciting heads up racing at a lower cost than custom built engines. It's an approach Chevrolet Performance implemented in a number of circle track racing series, providing racers with a high performance engine at great value.
The DR525 is designed as the spec engine for NMCA's LS Stock racing class in the LSX Showdown Challenge Series. The 6.2L (376 cubic inches) naturally aspirated engine is rated at 525 horsepower and features several tamper proof bolts to ensure class compliance. While it is the spec engine for the LS Stock class, the DR525 is legal in other classes and drag racing series.
GM19434599 includes a Gen 4 F-body oil pan (this installed oil pan will not work with muscle car LS engine swaps, oil pan change is required for muscle car LS engine swaps). Chevrolet Performance's custom calibrated E67-type control system - P/N 19432870 (sold separately, must use C10 fuel only) must be used with the DR525 in the LS Stock class. It features a tamper-proof engine control unit (can be used with other controllers).
