As we are talking about the '90 Mid Rise, Dual Plane intake manifolds for the 318s and the 2 bbl build applications.
Here is what the bottom side of the intake looks like. Impressive Yes.
And no tin shield underneath holding carbon bits from engine oil burning at the exhaust cross over path.
Pretty good clue as to the better flow capabilities of this intake as compared to the 2bbl dual planes of 1972.
Here is the bottom side of a 318/360 2 barrel intake manifold for comparison to the underside runners to the '90 318 mid rise manifold.
______________
Here is more of side shot of the same manifold '90 mid rise.
Shows the height of the mid rise and plenum section. Also shows the height of the runners and their added volume.
