Aggressive street/strip cams for Gen 3 Coyote that push power to the top end. Built around OEM-port heads, 5,800–8,500 rpm (≈8,100 peak). Spring upgrade required; DI/HPFP lobe retained; pump/race/E85–E90 ready.
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 to8,100 rpmonOEM-portheads. 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 ~5,800and pulls through8,500 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.
Profile intent:Aggressive Street/Strip with stronger top-end on OEM-port heads
Fuel:Pump gas, race fuel,E85/E90
Peak power:~8,100 rpm·Powerband:5,800–8,500 rpm
Valve springs:Upgrade required(use GSC-matched springs; Ti retainers recommended)
VCT:Tuner-managed phasing window recommended for high-rpm stability
DI fuel pump lobe:Maintains OEM lobe data for correct HPFP stroke/timing; compatible with factory and most upgraded DI pumps
Manufacturing:MADE IN THE USA; forged from proprietary U.S.-sourced bearing-grade steel, BLACK ISE surface treatment, CNC to tighter-than-OEM tolerances
Fitment:2018–2023 Mustang GT 5.0L
Tuning & Install Notes
Clearance:Always verify piston-to-valve clearance with your exact heads/pistons/gasket stack. With OEM pistons and deck heights, the full phaser range is usable without clearance issues.
Use upgraded valve springs (and Ti retainers) set to the tuner’s rev limit; check installed height and coil bind
See install sheet for torque sequence and procedures; prime oiling and fuel (HPFP follower inspection) on reassembly
