OakleyTankLines Posted November 7, 2013 Share Posted November 7, 2013 Where can i find the engine codes for my Straight 6? and where can i find a Spec sheet on it? 1978 Mack F-700( i think cummings) sleeper with double tandems. Quote Link to comment Share on other sites More sharing options...
farmer52 Posted November 7, 2013 Share Posted November 7, 2013 Your best source is the Mack Museum (link below). Send them or call with your serial number and they will provide you with lots of information including the build/spec sheet. A "nice" donation is appropriate for their work. Takes 6-8 weeks but well worth the wait.http://www.macktrucks.com/default.aspx?pageid=40Pics of the engine would help with identifying the model.

rsb502 Posted November 18, 2013 Share Posted November 18, 2013 EMD still makes 2 strokes in the US, cant fit em in a truck but theyre made in the USA! lol Quote "Any Society that would give up a little LIBERTY to gain a little SECURITY will Deserve Neither and LOSE BOTH" -Benjamin Franklin"If your gonna be STUPID, you gotta be TOUGH" "You cant always get what you want, but if you try sometimes you get what you need" Link to comment Share on other sites More sharing options...
rsb502 Posted November 18, 2013 Share Posted November 18, 2013 Hmmm actually I wonder if you could build a truck around one of the newer EMD V8 diesels, they were probably about 4-5' tall and 5' long about 4' wide and weigh around 4000-5000lbs.

Phase 1 Posted November 18, 2013 Share Posted November 18, 2013 I think Gray Marine (later became GM Detroit) an Fairbanks-Morse are the only US companys with 2 cy.BULLHUSKGray Marine used Detroit's for their marine conversions, but I don't think there was any other connection. Winton was the engine company that GM bought out that became the EMD locomotive diesel and I assume it was their experience with those that led them to design a two stroke truck diesel.The larger two stroke Detroit Diesels are still being made although I think it is done overseas now.
