305 and 350 intake manifold differences (supercharger adapter)

I'm wondering if there are significant differences between 305 and 350 intake manifolds? (I'm just too lazy to go look for myself) Here's the deal, I'm looking to put a GM supercharger on my Firebird's 350. A friend of mine is making an adapter for a Buick supercharger to fit on a 305. I was thinking of having him make me one of these adapters for me to do the same thing only with my 350. Would this work or is there obvious shape/bolt patterns?

Also if anyone's interested in one of these adapters (for the purpose of bolting on a Pontiac Grand Prix GTP or Buick Park Ave Ultra supercharger (m90) onto a 305 manifold) Contact me and I can refer you to the guy that's making them.

All SBCs use the same manifolds.
