[QUOTE="Codyj, post: 1184378, member: 17493"] Thanks for all the info. I probably highway drive about 40% of the time and when I tow its mainly on the highway. My highway speeds are usually around 120km - 130km With that equation i came up with: (70x(4.56X.71)x336)/37.7= 2019.85. @ 70mph or 112km OR: (77x(4.56x.71)x336)/37.7 = 2420 @ 77mph or 124km I lifted my truck and put 38's on it a week after i bought it, so i am unsure of what the stock rpms are at on highway speed. What do you think about the 4.56? is 2450 to high rpm? [/QUOTE]
