Engine date code help

I just purchased a 1989 YJ with a 258. The PO said that this engine came out of another Jeep but wasn't sure what year or model so I was hoping someone could help me out here and identify what year engine it is. I know that the first letter of the date code is the year but I'm not sure if it's a 1971 or 1981.

The engine date code is 109C30

Now I read in 1981 that they switched to a serpertine belt but I have V belts.

I have attached a picture of the engine also. Thanks for your help!
