GSC S2 Camshafts – 5.0L Coyote Gen 3 2018–2023 Mustang 5.0

When you want the Coyote to live on the big end, run S2. The GSC S2 profile is an aggressive street/strip cam set designed to carry power hard to 8,100 rpm on OEM-port heads. Ramps and events are modeled against real Gen 3 port behavior and rocker geometry, then cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. Built for pump gas, race fuel, or ethanol blends (E85/E90), with a powerband that comes on at ~5,800 and pulls through 8,500 rpm. 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. Expect stronger top-end than S1 and a rowdier character. This set is for builds that prioritize trap speed and track numbers over commuting manners. Tuners typically keep VCT online within a tighter phasing window for best results at high rpm.
