The Offenhauser 6284 High Performance Dual Port is the newest version of the legendary Offy Dual Port intake for the Ford 240 and 300 inline six. It updates the classic 6019 Dual Port with a redesigned plenum and divider and larger airflow passages. The goal is more top-end power and sharper throttle response without giving up the low-end torque that makes a 300 six great in a truck.

What's new vs. the 6019: The 6284 has a larger plenum volume for better high-rpm breathing, a redesigned divider for improved flow, and oval carb openings for smoother air/fuel distribution. If you loved the 6019 Dual Port, the 6284 gives you more volume, more flow, and more power.

Fitment: Fits all 1965–1996 Ford 240 and 300 inline six engines, in classic F-Series trucks, Broncos, Econolines, and custom builds.

Recommended carburetor: For most 6284 builds, we recommend the Edelbrock AVS2 650 CFM.

Comparing intakes? The Offenhauser 6227C-HD is the C-Series 4-barrel option and also works with Aces EFI throttle body systems.
