340 Manifold numbers question

I just got back from our local junkyard and found what I thought was a driver side 340 manifold and was going to use it on my 360.

The casting number is 3614395 and various web sites show this as a 1971-1973 340 manifold. I had a list with me when I found it.

But I have seen other folks say it is a 318 manifold....which is it and where is the bible of casting numbers found?

I used a list on MyMopar.com

Thanks much!
