When the 2 Club was established, the engines were flatheads, 4 bangers with overhead valves, GMC's and finally the hemis. By comparison 200 MPH today is a lark. Motorcycles approach 200 mph off the shelf. Door slammers go over 300. If the three pass record requirement was before your time, you have no idea of the added difficulty that generated. I know, the salt condition and time restrictions added to eliminating the third pass. It also greatly reduced the need for durability that in many instances isn't even achieved just making 2 passes.
If a person choses to run in a class where low speeds are records and they feel that their rewards are in the area of nostalgia, it would leave them outside of the window of accomplishments rewarded by the 2 Club. With todays technology, the availability of dynos, electronics, carb and injector technology, mega flame ignitions, chassis dynos and better metallurgy, it seems to me that the Red Hat should start at 250 MPH.
There may be some classes where just barely above 200 is credible but in a general sense, to approach the difficulty that was faced by a car, crew or driver in the past, minimums make sense.
