Does anyone know the torque spec? I'm about ready to change the oil and forgot to get it, the dealer couldnt help either.
On a side note I took the truck with the cabover on out to Estes park this weekend and the 6.2 did great. Cabover weighs about 2700 lbs and had no problem crossing a 12,000 ft summit using 85 octane. Was in 4th gear till near the top then I dropped it down to 3rd for the last half mile, no higher than 3500 rpm in third.
We recommend regular unleaded gasoline with a pump (R+M)/2 octane rating of 87. Some stations offer fuels posted as regular with an octane rating below 87, particularly in high altitude areas. We do not recommend fuels with an octane rating below 87.
