If you are asking questions like these, you should probably leave this to a professional.

thanks buddy.

if i could afford a pro i wouldnt be on this forum. i can follow directions well.

But can you turn a wrench?

yeah i can turn a wrench and im capable but i dont make it look easy. i have knowledge and understanding the physical side of things i struggle with. im a big big dude and everthing is harder.

Those motors, the 3800 II, they are solid motors, just a few issues you need to take care of and they should last 250-350k miles even.
You will want to go with the Aluminum framed gasket Kit, Felpro MS 98014 T
Make sure the coolant elbows are replace with the aluminum Dorman 47065HP coolant elbows.
And for the UIM you should not have many issues, but getting that aluminum upper intake to work right will take some work, you have to drill a hole in it for the PCV and, and I think the throttle body needs a spacer, I'll have to try to find some info on swapping that L26 UIM onto the L36, it can be done as I said, but you may just want to consider getting a new plastic UIM, as long as you replace the EGR stove pipe with the smaller diameter one you get in the LIM kit, and consider tapping and plugging the coolant ports on the UIM that go to the throttle body you would be ok.

Google L26 UIM to L36, you should see a thread on the Gran Prix forums, look at the pics and see what all the guy had to do to get the L26 UIM to work, it is a good bit of work.

William is giving excellent advise.
You should replace the rear main seal and the cover gasket in goes in while you have it
out.
Do you have the aluminum oil pan ?
If you do you have to use the oil pickup tube that came out of the old motor they look the same but you will find out if you don't the oil level sensor will hit the oil pickup and wont go in.
The aluminum pan also uses just silicone use ultra gray Permatex if that'* what you have.
