alex g Posted September 30, 2012 Share Posted September 30, 2012 Hi guy's I was wondering if anyone can tell me what my top speed would be for my truck.The guy I bought it from told me it was a 100mph truck.It is a 350 mack with a eaton 13 double over and 4.17 mack rearends and it has 24.5 rubber.I think from what I can find on the internet the final trans drive is .62.I haven't been able to try it out because when I bought the truck the cam was on it;s way out and needed to be replaced.I only drove it off the float and in to the shop.
