Vortex 218/227 Torquenorris
LS / LM7 3-Bolt Hydraulic Roller Performance Camshaft SMALLER BACE CIRCLE
The Redline Cams Vortex 218/227 Torquenorris is built for LS truck engines that need brutal torque, aggressive street attitude, and strong pull through the mid-range without killing drivability. Designed around the rugged LM7 5.3L platform, this cam wakes up stock or mildly modified LS engines with a deep, authoritative idle while still keeping excellent street manners.
The Torquenorris profile emphasizes instant throttle response and heavy torque production, making it ideal for trucks, street cars, and daily-driven performance builds that need power where it actually matters — from 2,000 RPM through 6,200 RPM.
With its aggressive lobe design and high lift potential, this cam dramatically improves cylinder filling compared to stock camshafts, producing the kind of hard-hitting acceleration LS engines are famous for.
