1993 Chevy Caprice Replacing 305 with a 350

Good Day!

I am replacing a seized 302 in my 1993 Caprice with an older 350. I would like to keep the car's fuel inection system, and simply beef up the injectors and pump, but I don't know if I will need to have the Electronic side "adjusted/replaced."

Also, how can find out if the transmission in the Caprice will work properly with a 350ci engine?

Thank you for your time!
