Chevy Small Block (SBC) Carbureted Aluminum Intake Manifold

If you’re looking for the right intake for your high-performance small block build, this dual-plane air gap intake may be the perfect fit. The air gap under the plenum helps keep engine heat from heating the fuel mixture in the plenum. This creates more power and torque. Like many dual-plane intake configurations, this setup offers the best throttle response and torque from 1,500 – 6,500 RPMs.

The lightweight cast aluminum intake is relatively low as compared to other dual plane intakes. If you’re looking for other intake offerings here at Karl Kustoms, check out this page. If you’re looking to take a larger step than just a replacement intake, consider our Connect and Cruise systems. You can learn about our Connect and Cruise systems in this post.

What’s Included

This 4.65″ tall manifold has a satin finish and includes head bolt adaptors. EGR is NOT included.

Important Notes

This dual-plane manifold will produce more power and torque comparable to single-plane manifolds. It retains the driveability and throttle response like other dual-planes and performs best between 1,500 and 6,500 rpm. Other features:
