We review the effects of an anomalous chromomagnetic moment on top quark pair production at the Tevatron for Run II. Apart from an overall rescaling by the total cross section these couplings have little influence on top production characteristics. We then examine how the exchange of a Kaluza-Klein tower of gravitons arising from the low scale quantum gravity scenario of Arkani-Hamed, Dimopoulos and Dvali influences top pair cross sections and several associated kinematical distributions. The data that will be available with Run II luminosities is shown to be sensitive to values of the effective Planck scale of order 1 TeV or more.
