What is the fastest speed you guys have ever taken your trucks? Not necessarially the 1/4 mile but if you have ever had an open stretch of highway to go wide open. My truck has just broke the 100mph mark today. That is pretty good for an over 5000 pound truck with the areodynamics of a brick. The truck has a 305 HO, SM465 so no overdrive, and 4.10 ratio with 35"s.
