hey iam looking into getting a new motor for my grand prix. It has a 3.1mpfi in it right now and i want the 3100 performance. Is it possible for me to put a 3100 in my car.

sure is, but you will only get like 20hp from that swap. If you are going to go through the trouble of a swap then do a 3800SC (L67)

go for the 3400 swap, if your looking for 3100. From what ive heard, the engines are pracitcally the same, just a bit more displacement.
