Maddog13407 Posted January 1, 2013 Share Posted January 1, 2013 pretty good powerwise. all the overhead valve gas Mack engines were. they had more grunt than a Diesel. fuel probably 3-5 miles a gallon on a good day haha. Quote Link to comment Share on other sites More sharing options...

Bigdogtrucker Posted January 1, 2013 Author Share Posted January 1, 2013 Were they good engines beisides the mpg's? Quote Link to comment Share on other sites More sharing options...
Maddog13407 Posted January 1, 2013 Share Posted January 1, 2013 believe the 464's, 540's and 707's were all good engines. def better than the flathead continentals in the smaller trucks. had more grunt than a 673 or 711 to. just different powerband with the gas jobs. wouldnt last as long as a diesel tho. just a little tough on fuel.

Freightrain Posted January 1, 2013 Share Posted January 1, 2013 Local guy has a gasser B(not sure what model/engine), he pulls a set of lil double flats. Very, very nice truck. He is very limited on road speed and it's VERY thirsty. Quote Larry 1959 B61 Liv'n Large......................

Maddog13407 Posted January 1, 2013 Share Posted January 1, 2013 yup, road speed is also an issue. some of my great grandfathers B62 SX's would run 52 mph empty and 52mph loaded tho. 464 with 20 speed quads. Quote Link to comment Share on other sites More sharing options...
Freightrain Posted January 1, 2013 Share Posted January 1, 2013 Well, it's been near 6-7 yrs since I've seen him or the truck. Owner was Terry Green, owner of Green Truck lines of Malvern, Ohio. He has retired and I think sold off the company.The truck was very nicely done, red/black, called it Mongo. Quote Larry 1959 B61 Liv'n Large......................

It was used daily to move excavating equipment in the NYC are until 1974. Very reliable , never any problems (unsure of engine size but it pulled a Rogers 20 ton capacity lowboy).Mike P.
