Possible Alero or Grand Am GT Project

Considering this past month or so I have been pretty active, mainly because my account was tampered with when you guys got hijacked awhile back and I've just got my password and account straigtened out. So with that said I've noticed that there can be some power made with the 3.4, granted I had the Ecotec prior and loved it, and I love the overall look of the Alero, but which would be a better buy between the 2, a GAGT or Alero? I know the gears are better in the GAGT and stock for stock the GA would beat the Alero, hell I beat a v6 Alero with my auto Ecotec Alero. Like I said this is a project, meaning heads, cams, exhaust, and other internal work will be done. In the end I wanna be runnin 13's, atleast, and hopefully N/A. Not sure if this can be done N/A, but I wanna try, regardless of what you guys say, I'm gonna try and get atleast close, LOL.
