Lmackattack Posted December 16, 2013 Share Posted December 16, 2013 Just about everything just depended on what model Mack Quote Link to comment https://www.bigmacktrucks.com/topic/33911-1977-era-mack-questions/#findComment-221681 Share on other sites More sharing options...

What about transmissions? Did Mack build an air suspension back then? What else did they have besides the camelback?Also, was the ENDT the same engine as an E6? Would you know the torque ratings? So far I've been consulting this:http://www.dwclutch.com/D&W/D&W%20Clutch%20&%20Brake%202/MACK%20TORQUE.pdf Edited December 16, 2013 by ajoso Quote Link to comment https://www.bigmacktrucks.com/topic/33911-1977-era-mack-questions/#findComment-221685 Share on other sites More sharing options...
