Gary Lewis Posted October 9, 2019 Share Posted October 9, 2019 A dual-plane intake for a 300 Six? Not sure I've seen one of those. What have I missed? Link to comment Share on other sites More sharing options...

Ray Cecil Posted October 10, 2019 Share Posted October 10, 2019 A dual-plane intake for a 300 Six? Not sure I've seen one of those. What have I missed? DUAL PORT, not dual plane. Theyve been available as long as ive been looking at them. Link to comment Share on other sites More sharing options...
Gary Lewis Posted October 11, 2019 Share Posted October 11, 2019 DUAL PORT, not dual plane. What's the difference? Looks like the two ports are on different, and dual, planes to me. Link to comment Share on other sites More sharing options...

Offenhauser Dual Port intake manifolds feature completely separate runner systems for the primaries and secondaries for more power across the rpm range. A dual plane does not descriminate against primaries and secondaries as far as I know. Link to comment Share on other sites More sharing options...
