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

So it'* not an on-off system like Honda'* VTEC, but actually constantly variable, more like the newer i-VTEC, that'* the best analogy I can give.
