How do I tell a 5.2 from a 5.9

Yea I understand that they dont supply anything. That was just a non thinking on my part. However, the seatbelt worked fine.

I did not know that its possible that u pull it in my area will allow swapping stuff around to build a complete engine. IF I go that route again I am pulling the heads to check for cracks and bore size. Thanks for the tip.
