💥 Overview
The Vortex 234 Street Venom is a high-energy street/strip hydraulic roller designed for Small Block Chevy engines running strong cylinder heads, good exhaust flow, and real compression. With 234°/234° @ .050", this cam delivers a vicious idle, brutal midrange torque, and clean top-end power that carries well past 6,800 RPM.
The symmetrical roller lobes provide strong cylinder pressure and clean scavenging, making this grind ideal for NA or mild power-adder applications. Now available in 108°, 110°, and 112° LSA, builders can choose between race-inspired lope, balanced street manners, or EFI-friendly drivability.
If your SBC needs to sound hostile and hit hard, the Street Venom delivers the bite.
