I think you've confused the KL-10 with the IBM System 360 Models 30 and 40.
There is no slower-speed variant of the KL-10 processor; speed ups were gained
by adding cache[1] and memory.

[1] A CitiBank operator, having overheard the systems folks discussing the
    upgrade from a 2040 to a 2050, answered a customer inquiry about the
    difference between the two as "Cash."  He was pretty much right.
