GSC R3 Camshafts – Gen 3 Coyote 5.0L (2018–2023 Mustang GT) – GSC7073R3
Extreme-RPM race cams for ported head methanol builds
The GSC7073R3 camshaft set is built for high-RPM, max-effort racing applications using ported Gen 3 Coyote heads. Designed to thrive in methanol-fueled setups, this profile delivers power deep into the 9,500 rpm range. Lobe geometry is modeled to match ported head flow and rocker motion, cut from U.S.-sourced forged billet blanks and finished with BLACK ISE coating for reduced friction and extended durability.
