The entire L98 induction system was designed for the 305. If you have a 350 it will most likely make more power with a larger TB, and certainly would make more power with a ported base manifold which to my knowledge does not have any specs on it, except you aren't supposed to modify it......... There is a lot of junk in the way inside the plenum, but it would be damn obvious to remove any of it if someone knew what to look for. Bolting a 58mm TB on a stock plenum will do nothing, the plenum opening is sized for the stock TB.
Not sure about the plenum opening on the LT1.
