Auto Parts: interchange, grand prix 3, lumina

Question
will a 3.1 out of a 2000 lumina fit in a 96 grand prix 3.1. motor and trans or just motor?

Answer
    The engine in the 2000 is completely different from the ones used in earlier years.  It has a different manifold and a completely different injection system.  I wouldn't know how many modifications you'd have to make for it to work, but it would be very difficult.
