I did this for the OHC teams and was curious about the CBC schools. This info is from the Ohio High School data base:
The site has the alltime record, scores for each game, most of the location (home, away, neutral), has conference/league records & standings for current and defunct conferences and the playoff records. It also has each schools record vs all of the opponents/teams they have played.
Here is the CBC schools records since 1972:

*****Not all of the home, away, neutral records equal the all time records for some schools as the site is still trying to get the home/away/neutral location for some games.
