I hate to burst your bubble, but you have the least desired Impala engine choice. The aftermarket is very small if not non-existant for the 3.4L. Plus their reliablility is horrid compared with the 3.8L Impala (Which has a massive aftermarket-market for it)

My best advice would be to keep it well maintaned as best as you can and wait to trade it on a different car. If you like the Impala's styling, trade the 05 for a LS or SS Impala that come with the 3.8L.
