Prowrench Posted August 17, 2019 Share Posted August 17, 2019 I watched a video which was a national geographic documentary on the Macungie factory. The documentary was in the recent past as they covered the Titan quite extensively. The Mack employee installing the bulldog explained that gold bulldogs go on a pedigree Mack and Chrome goes on a mixed breed or in other words one with components other than Mack. I purchased a 1970 steel dash R model in the early '80s which had a gold bulldog and I was led to believe back then that the gold bulldog was for Thermodyne engines and the chrome bulldog was for Maxidyne engines. Can anyone clear this up? Quote Link to comment Share on other sites More sharing options...
navypoppop Posted August 17, 2019 Share Posted August 17, 2019 Gold was Maxidyne way back and chrome was Thermodyne or other drive train. Then Gold was for all Mack driveline called pedigree and chrome was for others. Quote Link to comment Share on other sites More sharing options...
