Chevrolet Performance’s all-new DR525 sealed drag racing crate engine signals an important advancement for drag racing, enabling 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 a high performance engine at a great value.

The DR525 is designed as the spec engine for the National Muscle Car Association’s (NMCA’s) new 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. And while it is the spec engine for the LS Stock class, it is legal in other NMCA/LSX Showdown Challenge classes – and other drag racing series.

Technical highlights include:

• Lightweight composite intake manifold with a
90mm throttle body
• Two tamper-proof bolts incorporated on the intake
manifold, as well as a tamper-proof bolt on the
front cover and the oil pan
• Assembly includes production-type cast iron
exhaust manifolds; fuel rail and injectors; coil packs,
wires and spark plugs; LS3 water pump and damper
• A front accessory drive with alternator, drive belt and
more is available separately (P/N 19329418).

The DR525 is offered with two part numbers: 19370418 (includes Chevrolet Performance’s muscle car oil pan) or 19370417 (includes fourth-generation F-body oil pan). Chevrolet Performance’s custom calibrated E67-type engine control system – part number 19329003 (sold separately) – must be used with the DR525 in the LS Stock class. It features a tamper-proof engine control unit.

Note: Requires P/N 19329003 E67 Chevrolet Performance Engine control system w/custom calibration (tamper proof Engine Control Unit). Front Accessory Drive (optional) P/N 19329418 contains Alternator, Installation Hardware and Drive Belt. (Not Included w/engine assembly)
