Question Help me identify my engine/carb.....

Ok, I have a 1980 CJ-7 with what is supposed to be a 258 with 2-barrel carb (according to the VIN), and TF 999 Automatic.

I was hunting around in the books, comparing pictures, and found that I have a Carter YF 1-barrel carb and intake manifold installed (and running well, BTW).

So, now I'm wondering if this is the original motor or has one be transplanted by a previous owner. I can't find any reference to the Carter YF being used on a 258, only the 232.

The code stamped on the engine block is 308C10, so I assume the "C" is the same "C" in the VIN, meaning it is a 258 with a 2-barrel.

I'm thinking someone swapped out a 1-barrel manifold and the Carter YF, perhaps as a cheap fix for a crappy BBD. Also, stamped on the manifold is the number "8.7.78".

Is this a carb/manifold off a '78 I-6? Enquiring minds want to know...

Yes, the Carter YF was used on many 258s AND 232s. I had a factory one in a 1977 CJ-7 I had in the past, and a recent stock 1076 CJ-5 had one as well. If you search a chiltons or Factory Service Manual, you can find a list of what was used, and I have seen the reference to the YF for at least 70s 258s.
