Description

If you daily it and beat on it on weekends, this is your cam. The GSC S1 profile is engineered to wake up midrange and carry power cleanly to 7,700 rpm while keeping drivability intact. Profiles 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. Designed for stock (as-cast) heads and pump gas, race fuel, or ethanol blends (E85/E90).

Tuners keep VCT online for a civilized idle and crisp throttle; when you go WOT, it hits harder across the usable band—not just at the peak. 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.

The S1 also shines on the road course with naturally aspirated setups—delivering crisp throttle response out of corners and a broad, usable powerband that pulls cleanly without sacrificing drivability.

Specifications

  • Tune required to realize gains and maintain drivability
  • Events designed to maintain piston-to-valve clearance with OEM pistons and deck heights across the full phaser range
  • See install sheet for torque sequence and install procedures
  • For turbo setups, match with GSC springs and Ti retainers
  • New valve springs suggested for engines with more than 40k miles on the stock spring/cam configuration when installing cams

Specifications

  • Fuel: Pump / Race / E85–E90
  • RPM Band: 5,000–7,700 rpm (≈7,500 peak)
  • Valve Springs: OEM OK (NA/SC) · Turbo → GSC springs
  • Use Case: Street/Strip + NA road course
  • DI Pump Lobe: OEM geometry retained (HPFP compatible)

Product Details

  • Drop-in street/strip/track cams for Gen 3 Coyote that fatten the area under the curve without killing manners. Built around OEM as cast port heads, VCT-friendly, 5,000–7,700 rpm sweet spot; OEM valve springs OK for NA and blower, turbo compatible with an upgraded valve spring.

Features

  • Use case: Drop-in & street builds that want max performance under the curve at near-OEM peak power
  • Head spec: Optimized for OEM port cylinder heads (as-cast)
  • Fuel: Pump gas, race fuel, E85/E90
  • Peak profile: ~7,500 rpm horsepower target
  • Effective band: 5,000–7,700 rpm
  • Road course ready: Excellent for NA track builds; sharp throttle response and strong pull out of corners
  • VCT: Compatible; retains street manners with proper tuning
  • 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; from U.S. sourced billet, BLACK ISE surface treatment, CNC to tighter-than-OEM tolerances
  • Fitment: 2018–2021 F150 V8 Coyote 5.0L

Compatibility

  • 2018 - 2021 Ford F-150 Coyote Gen 3 (w/OEM Unported Head) 290/300 S1 Billet Camshafts
