Small Block ID

I bought a 68 small block from a good friend. He was not sure what it is. Came out of a 68 Malibu convertible. ID # is 3914638. It comes up as both a 307 and a 327 on various sites. Anyone have a history of knowledge about what it going on?

Besides pulling the head to measure, I'm not sure where or even if I need to go with this.

Re: Small Block ID

Get the other letters/numbers off the pad in front of the passenger side head.
That info will help narrow it down.
