lol your welcome, and its good to see someone realize the 3100 just doesnt have that potential unless turbo'ed.
as far as engine swaps go, you CAN swap a 3.8 s/c from a newer grand prix. that will require some custom work however. you would need the engine/transmission/pcm/motor mounts/maybe new transmission mounts and some wiring issues need to be worked out. also ive heard things about people having to cut a little into the firewall to make the headers fit.
if you go through with that swap, you will have 240 ish crank, and about 200 to the wheels. to get about 250 to the wheels you can look up research on this site from the 3.8 s/c section.
i believe there is a member who just swapped a 3.8 s/c into his gen 1 lumina.
just an fyi, itll take a bit of time and money to get it right.
check out w-body.com. they have a forum there and have alot more gen 1 grand prix's like us.
