Intake design for stock appearing class and needed a winter project

So I’m tired of paint and body work and it’s to cold to spray color now anyways. So I have embarked on tackling the intake on my car. I’m currently running a stock 68-69 340 intake with the divider cut down and the ports being blended and gasket matched. The car runs a stock appearing stock tire class. This requires the use of the stock casting intake. Everything from the paint down is free game. For me, there can be NO external changes. No casting one out of aluminum etc. I’m going for as close to a single plane intake with a more direct intake runner as I can do. Keeping in mind it ALL has to be hidden under the stock intake. I have removed the lower intake runner system which created a flat bottom with which to work with. Then I have remove the cast four hole section in the plenum.
