Will a 97 3800 series 2 fit in my 2002 Grand Prix?
They are both series II's, the engines are the same. GM updated the EFI on most vehicles between '99-'00. You will need to swap all six injectors and you may need to swap some sensors. There are also some other small brackets and accessories that may need to be changed depending on what the '97 engine is coming out of.
