1: An Edelbrock 7276 intake gasket on the lower intake. Expand for a look into what a port match will take on the unaltered as cast ports.
2: A look into the plenum and its port alignment and attaching stud. (1/4x20)
3: A look at the lower half and the different shape entrances.
4: I shoved the cell phone into the plenum from the bottom showing a very open area. (Perhaps not such a good shot as you need to tilt the head 90*'s.)
Measurements not exact! But close enough to call OK.
Manifold height Frt. 9, rear 10
Runner length as tape measured on the floor of the runner is 6-3/8
Port window, 1X2.2
Inside of plenum, 16x6-1/4x - 4-3/8 depth at the rear of the rear carb par and 3-11/16 deep at the front of the front carb pad.
Anything else! :)
