Welcome to AF.

Have you tried doing a search in the Grand am forum or the N-Body sections?
Thiers been lots of "talk" about thing but no specifics that I know of.

If you can get a 3.4 it should bolt up to the 4t60 transmission your 98' has.I dont know if the 3.8 would bolt up with out modifications.
I would stray from the 99+ automatic tranys, the 4t40-4t45E are terrible :

My 99' GT transmission(4t45E)has been giving me fits this past weekend,
and I'm about to throw it in a lake!

will i need and custom motor mounts or any other stuff like this for it to work. does any one know where i can find headers and intakes for it if i decide to keep the motor and built it up??? the only thing i dont like about it is that i never can find anything performance wise. its the 3.1 by the way

i was also wondering about this. if you did succesfully mounted the engine would all the sensors be the same or what? And would there be enough room to put on 01 OR Better headers?

If you are just swapping the motors then the new engine mounts need to be used. The problems occur when you have nothing to mount them too.

So at this point you'll need to fab a way to mount the engine mounts to the sub frame & trans.

On performance check these links.

Some 3.4 parts will fit the 3.1's, like the TB and maybe headers.
Good Hunting.
