You can run larger than 555. But you might get into idle and gas mileage issues. 555 are the max you cna have full control over. With a different engine you might be able to ocntrol higher or lower. Depending on what your CP ratio is and your ignition system. With tomei 555cc I was able to idle in the 14's and had perfect a/f ratio at all rpms.
