I have the part number for the injectors from a 350TBI, that I can swap into my LO3 without doing any custom prom. Do you think it is worth doing for performance increase? Or is it too much for my current mods?

You don't need bigger injectors with those mods. At the most you would need more fuel pressure. Look into getting the Vaccuum controlled fuel pressure regulator (there's a long post on this page about it). Even that may be too much. Look into getting an intake manifold, cam, and headers first, THEN worry about getting more fuel.
