Based on the multi-configuration Dirac-Fock method, the energy and transition parameters of C-like Al were calculated. Breit and QED correction as well as the effective volume effect of the nucleus and the nuclear mass correction effects were added to the Hamiltonian. The calculated data are in good agreement with the experimental values and other theoretical values. The calculated data compensate for the lack of spectral data and provide a theoretical basis for future researchers' experiments on Al VIII.
