  1. Macks version of a 8ll but only to be used behind a maxidyne motor due to large gear spacing compared to 9spd mack or fuller trans

    My new ride .

    haven't seen a sleeper mack truck with side pipes in years
  3. yep you can't hear a word what the factory did to make little over a hp per cubic in with a etec
  4. correct you could not get a mack trans. or rears in a vision till 2004 all pre emmision visions was mutts from the factory
  5. have you priced a reman motor from Mack they used to have a good warranty package, and it you would get a good cam that way. if you could chunk the egr system on that motor that would help reliability although that vgt turbo causes about as many issues as the egr and there no way around it

    MP 8 ?

    I figured the 338 would be kilowats and not hp

    When did Mack quit using the 237?

    no they made a EM6 225L as a replacement it did not have any chasie or engine mounted aftercooler. Don't think it was that common of a motor to spec 300 maxidyne was more common by the late 80s

    Heavy spec CH

    no frame is lighter and 14.6k is the heaviest front axle I belive you can get on a pinnicale but you can get heavy rears. slap on a set of beefy front springs and you could make a heavy truck out of one though

    EM7 upgraded inj and turbo

    did not know they put a 12speed behind a maxidyne motor

    EM7 upgraded inj and turbo

    if he goes bigger injectors and twists the pump wouldn't he end up with a 350hp or so maxydine?

    low range on the trans was mostly for creeping off road and curb side pouring in a cement truck you'll need the top 5 every time but the bottom 3 depends what you doing with the truck bet its at least for 5.73 gears in it
