Well, that's different!!!! I can help you there...
1. Is there a reenforcing web in the block casting about 2 inches above the oil pan? if so, it is a 308 block. If not, it could be a 232, or a 262.
2. on the side of the block, just in front of the manifold is the engine serial number. Get me that, and I think I can track it down for you.
