We were given a motor and trans. The people who gave it to us thinks it's a 390, but not sure. It has the yellow sticker still on the valve cover. It has 5 valve cover bolts It is a 1974 motor. What we aren't understanding is it says it is a 360CID but next to that it says Ford Family Identification: 360/390. So what is it? A 360 or 390. Any info is greatly appreciated! We need to know what size it is so we can get the correct parts.

Thanks,
Liz
