Thoughts On Fuel Distribution Dams (Intake Manifold)

Bobzilla said

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?

That is one big fix and 12many did a bang up job on his. Some of the distribution issues with the SD is directly related to the flange. That’s why I always weld them up and make them correct.

The first time I did it I found 12 average HP and IIRC it was 15 better at peak HP.

I am also playing with anti-reversion/shear plates as I think any time you can dampen reversion and shear the fuel better, you can run less fuel through the intake system, and less fuel in the system to begin with is always a better idea.
