GSC Power F150 Coyote Gen 3 Cam Set R3 Series Methanol
The GSC R3 is a max-effort, high-RPM profile for ported heads and methanol builds. It’s engineered to carry power where the Coyote lives on the limit, with lobe design modeled against ported Gen 3 cylinder head behavior and rocker geometry. Each set is cut from our U.S.-made forged billet blanks and finished with BLACK ISE for reduced friction and long life. DI note: the high-pressure fuel pump (DI/HPFP) lobe is kept to OEM spec for proper pump operation.
Highlights
Profile intent: Max-effort, high-RPM for ported heads and methanol fuel combos
Fuel: Methanol. Gasoline/Ethanol blended fuels wont reach peak powers with this profile.
Peak Power Active VCT: ~9,500 rpm · Powerband: 6,500–10,000 rpm
Peak Power Locked VCT:~8,400 rpm · Powerband: 6,700-8,400 rpm or...
Peak Power Locked VCT:~9,500 rpm · Powerband: 7,800-10,000 rpm
Valve springs: Upgrade required (use GSC-matched springs; Ti retainers recommended)
VCT: Tuner-managed phasing window recommended for best area under the curve
DI fuel pump lobe: Maintains OEM lobe data for correct HPFP stroke/timing
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 Gen 3 F150 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 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.
See install sheet for torque sequence and procedures; prime oiling and fuel (HPFP follower inspection) on reassembly.

About GSC Coyote Camshafts:
5.0L F150 GEN 3 Camshafts
You didn’t buy a 5.0 to blend in. Whether you’re staying NA, strapping on a blower, or chasing four-digit turbo numbers, GSC’s Gen 3 Coyote camshafts are built to hit harder across the entire RPM band.
These profiles aren’t guesswork—they’re the result of computer-aided simulation, decades of valvetrain engineering, and our proprietary port-balancing process that syncs valve events with real cylinder head flow. The result? Maximum lift, precise rocker geometry, and cams that keep VCT functionality so your Mustang stays civil at cruise and brutal at WOT.
At the core is GSC’s exclusive forged billet blank, made in-house from U.S. bearing-grade alloy steel—sourced from a single American mill for consistency you can trust. We finish every cam with our BLACK ISE surface treatment for friction reduction and extreme wear protection. Precision-machined on cutting-edge CNCs, these cams hold tighter tolerances than OEM and deliver repeatable, record-setting performance.
