I've never driven a Mack road truck so I couldn't say much about them. The only Macks I drove was in a quarry hauling crushed stone for the asphalt plant when I was 18. I think I have some old pics around here somewhere........

I can help out with specs, make rpm/mph charts, etc.. Nowadays the wrong specs can cost you 20k a year, easy. Something as simple as a direct drive vs overdrive, the direct drive tranny can save you 2k a year! If I was buying a new truck, it would have 2.64 gears, super singles OR XDA "energy" low pro 22.5's, a 10 speed direct drive ultrashift, or maybe volvos I-shift if I was going with a volvo engine. I talked to a guy running that combo, 12 speed volvo direct drive tranny, and a 485 D13, he said he was getting 7.5 mpg at 60 mph. Almost unheard of with a new 2008 truck! Anyone that buys a non-aero truck nowadays is nuts. If you INCLUDE spec-ing it'll probably raise this to 90%. :sad: I read of 2.73 rear-end gearing, BUT 2.64? Who manufactures 2.64's? What do you think about all these aerodynamic items they're experimenting with (walmart, et al - trailer skirts, baby moons, cab extenders, front bumper air dams etc.)? http://007planb.com/images/405-Giant-Ferrari.jpg |
