isn't that the truth.
if your looking to turn a f body into a dragster you'll have some serious chasis problems. i would go with a g body as well.
if your set on a f body i wouldn't set my sites on an iroc. if your going to gut it and tear it up you might as well just get a regular camaro you'll find it cheaper and your going to have to gut it anyway (susp,drivetrain etc...)
