sorry for making a generalization i was talking about the crappy 305 Iroc camaros that all the rednecks around here drive. we raced an '02 SS when that motor was in the fairlane and yah we got owned. i think a 406 galaxie can handle an Iroc and as far as the new GT mustangs from what i understand they weigh a ton i have heard some people say almost 4000lbs (i could be wrong)
