The COMP Cams OWM T/C CS 47S 289Hxl camshaft suits open‑wheel modified racers on 1/3–1/2 mile tracks with wide corners or slick surfaces. It’s intended for 355–383 ci engines with 12:1 compression and 4‑barrel induction, and it requires good intake and heads. The design emphasizes a broad torque curve to reduce tire spin while retaining top‑end power. Note: 1955–57 SBCs with a rear‑journal oiling groove need a different cam—contact us.
