I'm a new guy here. I just came across a 1976 454 .030 over. Nice oval port heads. Port matched, roller rockers. Flat tops etc. The camshaft is a Crane Fireball ll. Numbers are 132090. 302H. Does anyone have any specs on this? I know they were a popular application but I can't find anything on this on the Crane website. If anyone has an old Crane book from 1990 or so could you take a look? Performance warehouse used to sell these in there catalog also. Any help would be appreciated. Thanks
