Edelbrock Str Tunnel Ram 396-454 Manifold

This Edelbrock Street Tunnel Ram intake manifold is cast from durable aluminum and features a dual-quad, dual-plane design. It's specifically built for 396 to 502 cubic inch big-block Chevrolet V8 engines that use large oval-port heads, typically found in models from 1975 and earlier. The tunnel ram design is all about maximizing airflow to the cylinders at higher engine speeds, making it a popular choice for street machines, pro-street builds, and marine applications where low-end torque isn't the primary concern.

When you're aiming for serious top-end horsepower, this manifold is engineered to work seamlessly with performance camshafts. For instance, pairing it with the Edelbrock Performer RPM cam and kit #7162 is recommended to achieve the most potent high-RPM power output. The dual-quad setup allows for a substantial amount of fuel and air to enter the engine, supporting significant power gains when matched with the right carburetor setup and supporting modifications.

This manifold fits a wide range of Chevrolet and GMC vehicles from the mid-60s through the mid-70s, including popular models like the Chevrolet Impala, Chevelle, and C10 Pickup. It's important to note that this manifold is not CARB approved and cannot be shipped to California. Ensure your engine's cylinder heads are the large oval-port variety for proper fitment and optimal performance.
