Let's say a Motordyne 1/2" spacer with the hood spacer kit with an aftermarket plenum ON TOP of it.

Would this just be too much airflow in anyone's opinion?

Obviously use of any STB would be lost since I don't believe there is a STB with enough clearance for an aftermarket plenum + spacer.

The AAM angled spacer would give the front 2 cylinders TOO much airflow since the plenum would compensate for exactly the same thing the AAM would, but the regularly angled Motordyne would provide just an extra 1/2" of airflow, which can only help right?

This is just an idea I thought I'd toss out since we're trying to squeek every last HP out of N/A mods at this point.
