1988 305 TPI to 350 TPI
I have a 1988 305 TPI and obtained an almost new 350 crate engine real cheap. I would like to swap the 305 for the 350. I know I need different injectors and apparently a 350 knock sensor. Since the 305 and 350 fuel rails were different part #'s do I need 350 fuel rails as well or do the ones I have work fine with the 350 injectors?

engine swap thread would be a good place for you to look.

The only thing you will need to change from your TPI intake manifold on up is the injectors. Everything will bolt just fine on the 350.
