Is There a Car With an OEM Quick Ratio Rack?

[vette427-sbc]

As Jim Nilson was saying, look into C4 corvette racks (not sure if that was a typo Jim, but since '84, corvettes used only steering racks, no boxes).
Early C4's with the Z51 option had very quick ratio racks for a street car. I think they were somewhere around 2.25 turns lock to lock (They are front steer also). Anything quicker than that might feel a bit too twitchy.
