Yes I checked the passenger side, there are no numbers there. There is no ID pad I can find. I may not be looking in the right area. Zhandfull stated 68's have it near the bellhousing at 11 o'clock . . I haven't looked yet.
Top pad by the drivers head has an "F" which is 1970. That is there.
I was looking for any information I could find on this engine. What kind of car it came from would help. Would give a little history to it as I have nothing from previous owner.
