I am working on a complete spreadsheet for the M68K, but haven't been at it in a while. 68000 and similar are pretty straight forward, but from 68020 and up it's a little different with best average and worst cases depending on the previous instruction and the small caches. Most relevant is the User Manual to be fair the can be found on NXP's product archive.
