GM cubic inch limitations

I am in desperate need of some facts if anyone could help and printed ones would be even better.

The question was asked of me regarding the reasons behind Chevrolet not installing the 454 in Camaros and Novas from 1970 on. My understanding has always been that GM limited the cubic inch vs weight in the Camaros and Novas due to insurance issues and possibly sales infringements into the Chevelles and Impalas. Can anyone help with printed material or at least honest quotes from GM? I appreciate your help in advance.
