Built for ported heads and real track work, the GSC R2 profile drives the Coyote hard to 8,100 rpm with a usable band from 5,800–8,500 rpm. Events are modeled for ported Gen 3 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 on pump gas, race fuel, or ethanol blends (E85/E90). Direct Injection note: the high-pressure fuel pump (DI/HPFP) lobe is maintained to OEM specification—stroke and timing are retained for proper pump operation.
