Product Details

Haytalras Big Block Chevy Dual Plane Air Gap BBC Intake manifold Oval Port 396 402 427 454

Fitment note: Please check compatibility carefully before placing an order.

Description:

- The ope air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. So, the air/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Air-Gap manifolds, from idle to 5,500 rpm up to 1,500 to 6,500 rpm.

- Notes: Will not compatible with C10 pickup trucks

- Notes: Will not fit under the stock hood of a Corvette, 1965-67 Chevelle or 1967-81 Camaro.

- Notes: Please Check the Compatibility Carefully before Placing an Order.

Fitment & Compatibility

Use the product title, SKU, engine platform, and application notes as the primary fitment reference. If your vehicle has non-stock heads, intake setup, accessory drive, hood clearance, oil pan clearance, or swap mounts, contact Haytalras before ordering.

Shipping

Free standard shipping is available for orders shipping within the United States, excluding Alaska and Hawaii. Processing and delivery times may vary by SKU, destination, carrier, and order review status. Tracking is provided after fulfillment.

Returns & Warranty

Uninstalled, unused items may be eligible for return within 30 days after delivery. Keep the original packaging and contact Haytalras before sending anything back. Installed, modified, damaged, or fuel-contaminated parts may not be returnable.

Before Installation

Test-fit before final installation. Professional installation is recommended for performance parts. Check gasket surfaces, fastener torque, fuel and vacuum connections, sensor fitment, and hood or chassis clearance before starting the vehicle.

BUILT FOR REAL V8 PROJECTS

Performance parts buyers need fitment confidence, not guesswork.

Haytalras focuses on intake manifolds, oil pans, throttle bodies, and LS swap support hardware for street builds, classic muscle, and weekend track projects. Start with your engine platform, confirm the application notes, then reach out before purchase if the setup is modified.

Match SBC, BBC, SBF, BBF, Ford FE, LS, or your exact application before buying.

02
