I have a 3L with a st220 manifold and am going to have my buddy fab a intake for me since there needs to be a 45degree bend in the intake after doing the manifold. My question is the intake I have now we are working off of i s reduced where all the vacuum ports are. Would it be a bad idea to keep that section the same size through out? Was doing 65mm so it matchs my throttle body? Or is it reduced for some reason?
