Questions & Answers Ask a Product Question

Does this manifold fit the 23" or 25" Dodge flat heads? Also is the square plate on the bottom for the heat riser? There is no image showing the bottom of the manifold.

Asked by DWIGHT on June 08, 2016


I have a 1940 Dodge with the original flat 6 ( I don't know the block length ) and I got this intake which fit no problem. The square bottom is for the heat plate.

Does factory carb fit this? What aftermarket/performance carbs fit?

Asked by ARTHUR on January 05, 2019


Thank you for your question. The Offenhauser 2691 intake manifold will work with the OEM 1-barrel carburetors. At this time we do not offer any aftermarket 1-barrel carburetors for this intake manifold.

Do you have heat plate for intake

Thank you for your question. Offenhauser does not make a heat shield for their 2691 intake manifold.

Is this manifold water cooled?

Asked by DUANE on March 31, 2016


No, this manifold is not water cooled. There are steel freeze plugs on the bottom end that can be taken out and aluminum can be welded in their place if you wanted to convert it to be water cooled.
