What year is the 305 TPI?
'85-'89, you'll need to change the knock sensor and module. It would probalby run a little better if you put 22 lb injectors in as well. Some PROM tuning usually helps (helps a 305), but isn't absolutely necessary.
'90-'92, same as above but PROM changes are absolutely necessary.
