We present a full $pf$-shell spectroscopy of the low-lying states of $^{56}$Ni using the GXPF1A interaction.[M. Honma et al., Proceedings of ENAM, 2004] Both, the ground state band and the first deformed band, as well as the transition probabilities compares favorably with the experimental data.[D. Rudolpf et al., Phys. Rev. Lett. {\bf 82}, 5763 (1999)] We analyze the significance of the $np-nh$ contributions to the full model calculations, similar to the analysis done for $^{28}$Si in the $sd$-shell some twenty years ago.[Brown and Wildenthal, Ann. Rev. Nucl. Part. Sci. {\bf 38}, 29 (1988)]
