  1. Instill think your Gearing it too high, you get the rpm too low with your 2.56 rears and you'll lug and it won't pull for shit and fuel mileage will suck. Ask guys here what they are running and go with that. I also don't like the m drive but more for the "0" tolerance internals that will make the trans unrepairable only replaceable for a premium fee. I like bbigrigs set up of the MP8 445C, 13 speed 3.55 rears, only change I would make is low pro 24.5 rubber.

  2. Mack still has a very few pieces of the manifolds, if I can ever get a spare engine to do mock up work or get mine in a shop and take it apart for a while I'm gonna make tubular mailnifolds for the e9. I have a machine shop ready to laser cut my flanges already, we did the cad drawings last year now I just need stuff.

  3. For someone with an excavation company paying to haul equipment is gonna happen sooner or later. However when your not completely covered up and have time to move it with your own truck or need a piece moved asap being able to just load it up and move it is a big plus. Most of the people I know in that business have a truck and move their own stuff most of the time just because they can move it on their schedule not when the truck can get to it. Also if he buys a dump trailer he can not only use the truck to haul equipment but haul dirt and rock as well so in my mind its a huge asset to the company.

  4. Its a different torque rating from one to another engine and the clutch trans driveline and some rears have different torque ratings and using the minimum keeps costs down, to use an eaton 18913 transmission (1800# torque rating)instead of a 16913 (1600# rating) costs more and with the lower torque rating its considered a waste. I would order a new truck with the heaviest driveline clutch and trans available for a couple reasons, one you will be hard pressed to snap it off road, two if you uprate the engine or haul reakly heavy youll never overload the drivetrain.

  5. The pre scr engines like the 09 your looking at are pretty solid other than the 7th injector issues as stated before and injector cup issues. If its had the updates to all of that stuff it should be pretty decent. If not all you have to do is go to mack with the Vin and ask what updates or campaigns have been completed and what is available and go from there. The 425, 13 speed and 4.17 rears should pull great, I doubt you'd notice a lot of difference in uprating to 44. As long as the clutch trans and driveline are rated for the torque you can have mack update it all the way to 485 or 505 now, I doubt they're rated for the torque though. I'd say you found a pretty well specs truck for local work that should do a good job for ya but I can't see it from my house and there is a lot to be said for what a truck looks like.
