If you have any resto Catalogues, they have a lot of (car) specific info in them, including books. Most of the time, local book stores can get those books for you as well. Date code and specific numbers on blocks and parts can get a bit costly if the car is not original. But that depends on what you plan on doing with the car. A big block 454 crate motor is just as effective dressed up to look like a 427 as a real 427 itself. IMO, if the car is going to be a driver, take a 454 and dress it up to look like a 427. It will still give you a 425hp big block with out the dent in the piggy bank! Beautiful Camaro by the way and Welcome to the site!
