Another Newb Question!

Ok well i was driving the good ole 66 dart today, it has a 273 in it 4bbl. I came to a stop sign. When i went to go i kind of jumped on it and heard a loud clicking sound i panicked not knowing what happened even though i was still able to keep going. Decided to turn onto a little side street and have a look. Everything seemed to be ok. So i just went on. :/ Its my daily driver and i only notice the clicking noise when i jump on it a little now. Don't know what it is. Any input would help! Thanks
