is there an engine build date tag or something? how do I find my Engine build date? also I am having a driveline vibe.. any posts ? I might have missed?

Look on the driver's side of the valve cover. Should be a sticker/decal with hp, build date etc. Driver's door has another with the build date of the truck.
Plenty of posts on the vibration thing. Just scan down the threads or do a search.
Good Luck
