GSC Power Voodoo Cross Plane Firing Order Cam Set R3 Series - PRE-ORDER Now!
***Please Email us at [email protected] to let us know if you want to be notified when these become available***
The GSC R3 is a max-effort, high-RPM profile for ported heads and methanol builds. It’s engineered to carry power where the Voodoo lives on the limit, with lobe design modeled against the OEM ported Voodoo 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.
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 ~9,000 rpm · Powerband: 7,000–9,500 rpm
Valve springs: Upgrade required (use GSC-matched springs; Ti retainers recommended)
VCT: Tuner-managed phasing window recommended for best area under the curve
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: 2015–2020 Mustang 5.2 Cross Plane Crank
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 Voodoo Camshafts:
5.2L Mustang 5.2 Voodoo Camshafts
You didn’t buy a 5.2 to blend in. Whether you’re staying NA, strapping on a blower, or chasing four-digit turbo numbers, GSC’s 5.2 Voodoo 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.
