Most of the knucklebuster's around here are calling these formly tagged as Pony Cars with Muscle, the "New" Muscle Cars since the auto makers aren't offering much in the way of mid sized performance cars today, abet, even though several with V6's actually run better times than most of the old Muscle cars did off the show room floor.
Oh, almost all the old Muscle cars had the 14 inch rims and F & E70 (7.75 x 14) rubber, includeing the 450 h/p LS6 454 SS Chevelle's.
And I don't know if I can even consider the New GTO's as being representive of the Old GTO's, though I'd probably own one if the right price was there.
