The COMP Cams CS 45/28 H6 hydraulic camshaft follows a .450" lift rule for Chevy small blocks and delivers an aggressive idle with low vacuum, appropriate for race or high‑output street builds. It fits 262–400ci small blocks ('58–'02) in standard configurations; owners of 1955–57 SBCs with rear‑journal oiling grooves should request a camshaft made to that specification.
