Vortex 254/254 Ghost — LS 3-Bolt Hydraulic Roller Camshaft SMALLER BACE CIRCLE
The Vortex 254/254 Ghost is a high-RPM LS camshaft built for engines that are designed to move air fast, rev hard, and make power deep into the upper RPM range.
With a symmetrical 254° / 254° duration @ .050", the Ghost is engineered for maximum airflow efficiency at high engine speeds, delivering a smooth but relentless power curve that continues pulling well past where smaller cams fall off.
Despite the large duration, the Ghost’s lobe design maintains a clean, stable idle for its size, giving it a unique character — aggressive, but controlled. It’s a cam that doesn’t just sound violent — it builds power with precision and consistency at high RPM.
Designed for any Gen III / IV LS 3-bolt engine, this cam transforms LS builds into high-revving, race-inspired combinations built for serious performance.
