Be honest with yourself- If you are not gonna do alot of highway driving then go with the 4:10s. I had 29" tall tires with 4:10s and when I would get on the highway I was always bumping the B&M shifter thinking was in second when I was already in 3rd. Your 440 if it is a true 350 horse version is a torque freak and the 3:55s are a nice all around gear!
