F or 2F That is the question (1 Viewer)

Can someone let me know how I can tell if I have an F or 2F motor. Where would I look, And what do I look for. Thank You my brothers ( Jokers Welcome ) .

Should be on the passenger side of the block towards the back at least that's where mine says it ..F4334923 somthing something

Your username implies you have a 1971 Model FJ40, located in Arizona. If it is the original engine to your truck- it is a 1F. 2Fs weren't available until 1975.

It's not the original motor. It was left to me from a family member that past, so I don't know what he put in it.

If I am not mistaken.....the quick way for a novice to judge is look for the oil filter....on the passenger side for a 2F.
