Default Engine I.D. help needed.

I'm looking at a casting #3858174 on the rear of the block.

Heads have a casting #3917291.

What do we have here?... Thanks.

The engine block is a 327 CI from '64-'67, and has 2 bolt mains.

The heads are from '67-'68, from either a 302, 327, or 350. They are camel hump heads, with no accessory holes and have 64cc chambers.

Looks like someone's rebuilt this one. Not a bad set up. Thanks
