The COMP Cams 293QIO10 hydraulic roller is aimed at street/strip 454–502 c.i. engines with quality cylinder heads, and typically needs about 9.5:1+ compression with a 3000+ rpm stall converter or a manual transmission. It delivers strong power in heavily modified big-block applications when matched with appropriate intake, exhaust and gearing for the build.
