What year is it
Check the numbers on the front of the block, just under the cylinder head. You will likely need to scrape the area or hit it with a wire brush. Here is the info from a Mopar book, and then an example of the numbers from a clean block so you know what you are looking for. I agree with Locomotion that is probably 97, and the numbers at the front will support that if you find the first digit is a 7.
