The 2.70 refers to the 'core thickness'....this radiator was unique for the Nova that year. All the Gibb COPO Novas came equipped with the HD 2.70 4 core unit. In 68-70 the tags were similar between Nova and Camaro...this link will show you the tag/codes.

The Gibb Nova advertisements mention the special 2.70 radiator
