    What you said about the rough sound is right! Especially when they’re started from cold with newly rebuilt injectors – you can hear the distinct idle clatter from the governor!


    PS: Will send ya a link to another YouTube vid from a mate of mine who has a 1969 Kenworth LW924 and you will hear what I’m on about!

    Brad…Wouldnt be interested in selling that 9500, would you?

    Yes Jim,I would and for a small fee of only $2500 cash. It’s an ex Mclean truck and it does have some rust,but very restorable.The engine is as clean as can be. I even have a Brigadere? hood you can have with it.

    Darn….Thats a good price, I’m looking at my map now to see how far apart we are.I dont have a trailer big enough to haul it, and I I wouldnt want to risk driving it..I am in in Indiana and have a friend Steve Shaffer thats a collector who might possibly pick it up…He runs long haul for Star..and picks up his antiques..possibly he could pick the GMC up for me.. I will follow up on this..

    im getting a 1977 but it has a 671 in it

  13. ClassicTVMan81 September 22, 2009 at 6:30 am #

    6V-53 is ruled out (those were used in the lower-rated 7500s and 8000s); I have to say 6V-92T(A), even though the 6-71N seemed to be more common in the non-Brigadier 9500s.

    A few Brigadier 8000s also had the 6V-53N (from 1978 to 1980) and the 6V-53T (from 1980 to 1984).

    Two stroke sound and when properly tuned and maintained these two strokes get four stroke fuel milage. They seem to have fairly clean exhaust when running properly too. EMD used this basic design on locomotive engines, after all they were both owned by GM once upon a time.

    correct and them 2 stroke SW1500 are still runnin today too.

    That’s definately a 6v92TA

  18. nachos1990 December 13, 2009 at 11:53 am #

    actually sounds like a 6v71 not a 92

  19. MegaZsolti January 3, 2010 at 8:17 am #

    Sorry Hotrodx199, but I think that is a 6v71 too

    1978? wow I always thought they were older. The one prior that used to carry the GM cars painted light blue By a carrier called Gateway Carriers* I think. After they stopped using them in the later 70s they went to the Brigadier with that same aqua blue.

    Think she would pull the 53` 4 axle trailer around the landfill? Its at least 100,000lbs gross. I guess with the right gears it could do anything!
