Haytalras 3026 Chevy BBC Air-Gap Dual Plane Oval Port Intake Manifold 1966-2000 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.
