The Edelbrock Performer RPM intake manifold for 1955–1986 small‑block Chevrolet engines blends single‑plane power feel with dual‑plane throttle response to deliver maximum power and a broad torque curve for high‑performance street and marine use. It accepts late‑model water necks, A/C, alternator and HEI, and may be machined for an oil fill tube; note it may not fit under some stock Corvette hoods or 1987+ cast‑iron heads.
