Since founder Vic Edelbrock Sr. began building performance intake manifolds in 1938, Edelbrock has grown into one of the most trusted names in American high-performance parts, from carburetors and intake manifolds to cylinder heads, crate engines, and EFI systems. JEGS has spent decades supplying Edelbrock components to racers, engine builders, and street enthusiasts, backing this extensive lineup with in-house technical support, fast shipping, and a Price Match Guarantee so you can choose proven Edelbrock parts with confidence.

Designed for high-performance non-emission 1965-76 Oldsmobile 400, 425 and 455 cubic-inch engines with Torker 455 manifold #350-2730. This head features an improved 77cc combustion chamber design that increases the quench area for a more efficient burn. This results in outstanding horsepower and torque.

These complete heads are assembled and ready-to-run with stainless steel 2.072'' intake valves and 1.680'' exhaust valves, hardened ductile iron valve seats and phosphor bronze guides. The valvetrain has been upgraded from the factory pedestal-mount system to a 7/16'' screw-in stud and 3/8'' pushrod-slot guideplate for increased valvetrain stability.

The high-velocity, factory location ports feature 188cc intake runners and 106cc raised-floor exhaust runners for substantially improved flow and increased power. Head bolt holes are drilled for the stock 7/16'' bolts, but can be easily modified for 1/2'' bolts or studs by drilling the 1/2'' counterbore. Aftermarket rocker arms and hardened pushrods are required for installation. These heads will fit 350-403 Oldsmobiles with Edelbrock manifold #350-7111 only (port matching required). Made In The USA!
