I'm surprised Mchell that with your 71-72 GTO hood you haven't tried the same air cleaner my Formula has. They are reproduced and aren't overly expensive.
I found similar differences with my Chevelle and it's cowl induction setup. The difference in IAT temps is night and day.

My 71 hood is capable of using the same ram air setup that was used on 71 gto’s and the formulas.
However there are trade offs and complications associated:
- the rpm intake sits A LOT higher, throwing the sealing geometry off and likely not allowing hood clearance for the air cleaner at all
- the pan and air cleaner assembly is weighty, possibly negating any benefits
You did give me an idea tho. Might try sealing the forward edge or back edge of the air cleaner base to the hood with foam to figure out if it likes air from the front of the engine or the back. Might reduce turbulence as well.
Can only try.
I am going to try a mock up of the the Jim hand carb mod to improve air flow into it.
