Description

Built for ported heads and real track work, the GSC R3 profile drives the Coyote hard to 9,1k-9,6k rpm with a usable band from 7,000–10,00 rpm.

Events are modeled for Voodoo heads flow behavior and correct rocker geometry for high-flow combinations, then cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. Runs best on Methanol Fuel.

Install notes

  • Clearance: Always verify piston-to-valve clearance with your exact heads, pistons, and gasket stack. With OEM pistons and deck heights, the full phaser range is typically usable without clearance issues.
  • Use upgraded valve springs (and Ti retainers) set to the tuner’s rev limit; check installed height and coil bind.

Specifications

 

  • Fuel: Methanol
  • RPM Band: 7,000–10,000 rpm (≈9.1–9.6 peak)
