Cool bacon wrapped pork loin in slow cooker

Quick question…I found a recipe for a bacon wrapped pork loin in a crock pot. It called for 3 lbs of pork and said to cook on low for 4-5 hours in a crock pot. I was only able to find a 1.4 lb pork loin. Should I still put it in a crock pot for 4-5 hours on low? What is your recommendation and what should the final temp be?
