71 duster / edelbrock airgap ?

I had an airgap, 1" spacer, 1850 Holley in my 72 Duster. Fit fine with a 14 x 3 filter and drop base.

If you have the intake on it now (not sure by reading the first post), Measure your clearance with some play dough balls around the perimeter of the air cleaner and on the middle stud. Then measure the height difference in the carb you want to run.
