My 64 Maxwedge ran almost the same with a stock hood as with a sealed Six Pac type. Don’t know why they worked but the rage at that time (70s) where newspaper boxes. They just worked, especially on tunnel rams, just cut carb holes and and long rod to hold them on. Prerunner to the Jimmy Durante nose.
They were simple with a minimum of fabrication, they were sealed and they were free.
If the results don't match the theory, change the theory.
