Anyone have any idea how much taller than stock the deck height of an air gap manifold is? Did lots of measureing today to see how much space I have between hood and air cleaner. Bought a Edelbrock Pro Flow cleaner today, it gives me about 1.75" more room. I have about 2.375" to play with before hitting the hood, is this enough?

Edelbrock has the height measurements of all their manifolds posted on their website. Simply check out the specs on the AirGap manifold and compare against your stock manifold. The measurements are very simple, and come off the forward and rear surfaces of the block.

I run a 1/2 inch taller setup under a stock height hood.. I use a 1 1/4 inch drop base with a 2 1/4 inch filter..

Thanks, got the measurements I needed. Never noticed the specs on these pages before..........too busy drooling!
I'm currently running a SpeedDemon 750 on a Qjet Performer intake, so I'm using an adapter that is about 1" tall (you know the thickness if you've seen one before) I'm using a dropbase aircleaner to accomplish this. SO anyhow, if I swap to an Airgap/RPM manifold where I wouldn't need the adaptor, am I going to be good? or is some kind of super-lowrise required for that? Stock 77 hood.

The air gap shows to be .700" taller than the performer manifold, which is 1.05" taller than stock. I still have a stock manifold on my 77 with stock hood. With a 14" x 3" air cleaner, I have 1.175" clearance at the front of air cleaner (point of least clearance). The air gap will eat up 1.05" of the 1.175" clearance leaving .125" clearance at the front. I don't know about the SpeedDemon carb height but if it is the same as stock q-jet height you should be alright without a spacer/adaptor. To find my clearance, I took a Coke can and drilled a hole in the bottom of it. Then kinda pre-squashed it a little to make sure I didn't hurt the hood. Turned my air cleaner cover up-side-down and placed the can over the air cleaner stud. Next I shut the hood and the Coke can took the shape of the hood along with the angle of hood slope. From there I calculated the clearance at center of carb and the angle of hood slope. With this information you can determine if you have clearance with different size air cleaners. Very simple process, hope I haven't made it sound too complex!
