Thoughts On Fuel Distribution Dams (Intake Manifold)

12many said
Of all the single planes guys here are using, many showing their porting work and plenum modifications, Ive yet to see any with dams. So knowing that one can only assume this is an old trick used back in the day and as YR mentioned there are other ways. Nothing I’m doing in the foreseeable future only a curiosity

Yours is the one with the epoxy to re-form the plenum into a regular square bore, isn't it, from another thread?
I wonder if that helps some of the distribution issues in the base casting, making the Mopar air dams less necessary? Maybe that is one of the ways yellow rose was mentioning can help take care of it?
