💥 Overview
The Vortex 234 Street Venom is the bite your Small Block Ford’s been waiting for — a sharp, aggressive street/strip cam that blends top-end pull with venomous midrange torque and an unmistakable lope.
With 234°/234° duration @ .050", this grind is designed to push high-flow heads and free-breathing exhaust systems to their full potential. The Street Venom’s symmetrical lobes deliver explosive throttle response and clean overlap for crisp scavenging and power through 6,800+ RPM.
Available in 110° and 112° LSA (installed 4° advanced), it gives builders the choice between an aggressive, race-inspired idle or smoother EFI-compatible performance — without sacrificing that trademark Vortex attitude.
