Product Details

  • Engine
  • The most powerful supercharged COPO crate engine is designed for NHRA's A Super Stock class and uses a large, 4.0L compressor to generate tremendous horsepower. Its foundation is the sturdy LSX cylinder block, with a tough, all-forged rotating assembly and the big-displacement Whipple blower. Like the other COPO crate engines, this one uses the high-flow LS7 heads to move as much air as possible.
