Info

A new classic – the LS3

As the standard engine in the fifth-generation Camaro SS and C6 Corvette, the high-revving, deep-breathing LS3 6.2L is poised to go down in history as one of Chevrolet’s best and most versatile engines.

Modern Muscle 

The LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio.

  • 6.2L
  • 376 C.I.D
  • 430 HP @ 5900 RPM
  • 425 LB/FT @ 4600 RPM
  • Aluminum Cylinder Head Material

Notes

  • Corvette 14-inch automatic transmission flexplate included
  • Non-Corvette applications will require purchase of flexplate or flywheel
  • Controller kit sold separately: item 35519354328 (for non-Corvette/Camaro SS applications)
