The period of a simple pendulum is independent of amplitude *for small amplitudes*. Recall that the derivation of the pendulum formula uses the small angle approximation sinθ ≈ θ (radian measure, of course). As the amplitude increases, you'll get a greater period. (And I suppose air resistance will have a greater effect as well.)
