The race-ready LS built for the strip

 

Meet the DR525 crate engine. It’s an iconic small-block LS3 6.2L with the powerful ASA camshaft, and now in
a competition drag racing application. The engine comes factory sealed so you can go from the crate to the staging lanes in minimal time, with no modifications. Initially designed as the spec engine for National Muscle Car Association’s new LS Stock racing class, the DR525 is the perfect choice for spec-class racing or if you just want to update your bracket-racer with an electronic fuel-injected powerhouse.

 

On the inside, the DR525 crate engine is built out with components designed to meet the high standards of competitive racing. The 376-cu.-in. 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.
