Well, you didn't say what the difference between your sim and the real circuit is, however, with the parameters in the .Model statement, both q1 and q2 are not biased correctly, and the input is overdriven.
Do .OP solution, and you will find that q1 is saturated (Rb1 is too low, should be ~200K), and to center the voltage swing, q2's bias should be adjusted, too (RB3 should be ~160K).
With the bias problems fixed, the largest input that will not clip is ~70mV.
Ri shunting the input voltage source is redundant. Why are there two load resistors Ro & Rload in parallel?
