The Edelbrock Performer RPM polished intake manifold for 1955–1986 small‑block Chevrolet engines blends single‑plane power characteristics with dual‑plane throttle response, offering a broad torque curve for street and marine use. It accepts late‑model accessories including HEI and has provision to machine for an oil fill tube, while delivering a polished finish for classic show appeal. Note that it may not clear some stock Corvette hoods or 1987+ cast iron heads.
