No problem, that is what I did after making the mistake of mixing the '86 pan with the 3.4L timing cover.
And just so the OP knows his options, you can use the 3.4L oil pan and the 3.4L timing cover with the 3.4L water pump as long as you swap out the metal impeller for the one on the 2.8L water pump. You cannot use the stock 3.4L water pump as it's reverse rotation to the stock 2.8L water pump and will cause overheating. Don't ask how I know this.
Pressing the old impeller off and the new one on is an art that I have not mastered. Once I broke my impeller I gave up. Water pumps are cheap but I didn't have the right tools and just messed things up.
3.4L water pump at the bottom, 2.8L at the top.
