james j neiweem Posted Thursday at 04:47 PM Share Posted Thursday at 04:47 PM Were there common engine blocks for various Mack engines such as: 672(Lanova)-673-711(707 gasser)-675(Maxi) 675(Maxi)-743(stroked) 531(gasser) 707(gasser) 864-865-866-E9 Was the 743 block Mack's or Renault's Was the Mack big six a one of a kind block- (should have stuck with developing this and dropped pursuing the V8's) although the E9 was eventually a good engine, all the other manufactures had success with the inline sixes. Detroit was an exception with their successful V series (emissions got them in the end) Quote Link to comment https://www.bigmacktrucks.com/topic/75416-mack-engine-blocks/ Share on other sites More sharing options...
