you can always get a chip... and the 8.1 and the 6.0 are only offerd in the 3/4tons... and 1/2ton HDs. (6.0L) its rather complicated.. Cuz you didnt say what year it is.. or if it was an 8lug...

First of all, im talking km/h. The reason I dont go that fast is the Fuzz is really bad around here. Second off, it was the previous gen to the new ones, so im guessing 5.7L, althought I wouldnt rule out the 7.4L.

My dad owned a long box 2x4 with an extended cab and a 4.8L for the past 2 years before getting the Aurora. You cant merge with them. He had a pair of Toyo tires on it, and he could spin through all of first, without WOT.
