if the 350 is mild you can use teh stock tb and injectors. if you 350 is going to be a step or two up from stock you will definately want to go with a little bit bigger injectors.
the only time you woudl really "need" a larger tb is if you are going for a lot more performance, any time you are trying to get above 300hp i think it is a good idea. below that level the stock tbi with ultimate tbi mods will get the job done.
