Edelbrock Polished B/B Chevy O-Port RPM Air-Gap Manifold

If you're looking to get the most out of your big-block Chevy engine, especially one built for street performance with oval-port heads, this Edelbrock RPM Air-Gap intake manifold is a solid choice. It's designed for 396 to 502 cubic inch engines and uses race-winning technology from Edelbrock's Victor Series manifolds. The key feature is the Air-Gap design, which creates an open space between the intake runners and the hot engine oil. This keeps the incoming air charge cooler and denser, which translates directly into more power for your street-driven machine.

This manifold is well-built with a polished finish that looks fantastic under the hood, giving your engine bay a classic, show-ready appearance. It's designed to accept late-model alternator and A/C brackets, making it practical for street applications, and it's set up for square bore carburetors. You'll find rear water outlets, dual distributor clamp locations, and bosses for nitrous if you decide to go that route. Keep in mind that it won't fit under the stock hood of certain Corvettes, Chevelles, or Camaros, and it doesn't have provisions for exhaust heated chokes or crossovers.

This manifold is a popular upgrade for a wide range of Chevrolet vehicles from the 1960s through the 1980s, including models like the Impala, Chevelle, and C10 Pickup. It's a substantial piece that can help maximize the performance gains from other engine upgrades you've made.
