I'm looking for a semi to haul grain and I found a couple of Mack options. One with the ACEL 380 and another with the ACEL 427. I think I'll have enough hp either way but I am wondering about the reliability of these motors. What is the good and bad of these and how many miles is usual for them to need an overhaul. I'm looking at '06 and '07 models. Would you choose one over the other or are they something I should be steering away from entirely?
