Vortex 240/245 Power Shift — LS 3-Bolt Hydraulic Roller Camshaft SMALLER BACE CIRCLE
The Vortex 240/245 Power Shift is a high-output LS camshaft engineered for builds that demand hard midrange acceleration, strong exhaust scavenging, and relentless top-end power.
With a split-duration design of 240° intake / 245° exhaust @ .050", this cam is designed to maximize cylinder evacuation and airflow efficiency, making it ideal for engines with ported heads, long-tube headers, and high-flow intake systems. The added exhaust duration helps pull harder through the upper RPM range, delivering a violent charge past midrange into high RPM.
Designed for any Gen III / IV LS 3-bolt engine, the Power Shift transforms LS builds into aggressive, high-revving street/strip combinations with a deep, choppy idle and serious power potential.
