the only thing that you would really be changing is the injectors. The 305 and 350 TBIs are exactly the same (1 11/16" bores), but the 305s have 45# injectors and the 350s usually have 55# injectors. Unless you have a number of mods, you should be fine just doing the Ulitmate TBI mods and increasing the fuel pressure alittle.
