So somebody educate me. The Z/28 RPO was developed from 67-69 to allow GM to run these cars in Trans Am racing, and the 302 that was part of the package was developed to meet the displacement limit for the class the cars ran in. So why didn't Pontiac develop a small displacement version of the 400 for the Trans Am package? Was the T/A not developed for this class? Just curious.
