Why does one remove the plenum divider? I have seen this before and always questioned it, one manifold that I had years ago had a bid square notch cut out of it?
It was developed as a “Cheat” for the rules of “Must run a dual plane intake manifold” because what your doing is trying to create one within the confines of the casting so it will work with a cam known as “A BIG cam!” and “BIG *** Cam!”
