Never actually tested it in place but rough measurements put the thickness from the font face of the shroud to the back of the fan at 3.25"
From the rear face of the radiator shroud mounts to the pulley is (roughly) 6"
So the thickness of the fan at it's highest is still less than the max thickness of the factory 460 shroud.
Happy to get other details if needed. If really serious about it, I can pull the fan and install it.
