The Vortex 294 Street Reaper is built for Small Block Chevy guys who want vicious mid-to-top-end pull, a deep-cut lope, and raw street attitude.
If you’re chasing that “this thing sounds pissed off” idle while still keeping hydraulic-flat-tappet reliability — this is the cam that delivers.
Designed around 244° @ .050 and 112° LSA, the Street Reaper hits hard in the 3,200–6,400+ RPM zone, making it a perfect match for high-flow heads, deep-breathing exhaust, and aggressive weekend street/strip builds.

❗ Notes for Builders
Ensure proper break-in with high-zinc oil and dual springs removed during break-in if using high-pressure springs.
Expect a rowdy idle — this cam is not meant for stock drivability.
Works extremely well in tight-quench, 10:1–10.5:1 compression builds.
