Either way, the 3500 makes at least 200hp, don't remember the exact number but I think it was just over 200hp. Should be pretty reliable as well since its based on the 60* platform. I imagine those cars would run high 15'*/low 16'* with that engine due to their fairly light weight (compared to a Bonnie anyways).
Some g6'* (maybe even the coupe) weight as much as my bonnie does.
/runs off to check
EDIT: From pontiac.com We have iron engine, they do not. Strip both engines out of respective cars, the bonne could be lighter depending on what year you compare. Heck a 1983 Bonnie was 100lbs lighter then my 1993 in race trim.
G6 Curb weight, lbs 6cyl=3,420 GT = 3,425
