Carrillo pistons are manufactured to exacting tolerances and designed for serious performance engines where reliability and power are critical. The dome configuration provides optimal flame propagation and enhanced compression for maximum power output. These pistons are ideal for race engines, stroker builds, and high-compression street/strip applications requiring pump gas or racing fuel compatibility.

Note: Final compression ratio will vary based on actual cylinder head chamber volume, deck height, and gasket thickness. Professional engine assembly and proper piston-to-wall clearance setup recommended.
