...Larry, I have one out in the Garage, still in the box.
I'll get out there in a Little while and post the Measurements for You.
I will say this....The Air-Gap Dual Plane is a very well engineered Intake. IMO
...We know these Manifolds are intended for the Cleveland, Mounted in a Mustang, or Other Front Engine Vehicle, so the Carb Mounting Pad is at a 5 Degree Angle, Down in the Front.
These Measurements are taken Between the Gasket Surfaces of the Block, to the Carb Pad Surface at the Top of the Manifold, at the Front and Rear. See Pics, The Measurements are,
Manifold Pad at the 5 Degree Angle:
Front= 4-5/8"
Rear = 5-3/4"
...WITH the 5 Degree Angle PLATE Installed:
Front= 5-7/8"
Rear = 5-15/16"
I DO NOT think there will be a Clearance Problem with the Engine Cover.
...And when the Plate is installed the Slight Angle to the Studs is Minimal. I have done this before. Just use Studs with a Metal washer Under the Nut...BUT use a Thick FIBER Washer under the Metal Washer. This Allows tightening the Nut without much undue stress. NO Need to re-Drill the Stud Holes. It is 'Forgiving', the Carb will Seal Just Fine.
MADE IN THE USA
This Air-Gap Manifold looks to Me, No Higher than the Torquer Single Plane Manifold.
NOTE: Always Use STUDS. Some have used Bolts at the Carb, in My Opinion, Not a good Idea! Studs make the Assembly Rigid and Locate the Carb more Accurately.
Last...We can expect the 'Air-Gap' to run cooler as the Runners are Isolated, great for Operation during the Summer Months.
But since there is NO EGR/Heater Passage, I would expect it to run 'Poorly' in the Cold Air of Winter. Cold is Not conducive to good 'Atomization'! Be Aware.
