The COMP Cams solid cam with a .500" lift rule runs under 10" of vacuum and produces a rough idle while offering very good power. It’s targeted at builds that accept less vacuum and rougher low‑speed behavior in exchange for stronger top‑end performance. Proper valvetrain components and careful tuning are recommended to optimize reliability and extract the highest usable power from this aggressive profile.
