h67st Posted July 24, 2017 Share Posted July 24, 2017 I saw this B on ebay with a Cummins...I recognize the fuel shutoff solenoid, but not the valve cover! What Cummins is that? http://www.ebay.com/itm/1956-Mack-/152635252513?hash=item2389c51f21:g:L8oAAOSwW9ZZdNeg&vxp=mtr Quote Link to comment https://www.bigmacktrucks.com/topic/50539-b-with-a-cummins/ Share on other sites More sharing options...

james j neiweem Posted July 24, 2017 Share Posted July 24, 2017 (edited) Those 672 Cummins were popular in the early White 9000 coupe cabs and later the 743 Cummins (220 HP). The early white 9000 was a strong competitor to the B-61.

Were the 5sp only available in the 237 and 285? What did the 300 and 350 come with 9sp and higher?

Maddog13407 Posted July 28, 2017 Share Posted July 28, 2017 there were a lot of real 300's around new England that always seemed to have a 9 speed roadranger in them. dunno if this was just the spec? every 300+ I have seen had a 10 speed roadranger.i don't think that was the only option. most 237's 250's and 275's had 5 speeds, least the ones I have seen Quote Link to comment https://www.bigmacktrucks.com/topic/50539-b-with-a-cummins/#findComment-376029 Share on other sites More sharing options...
TeamsterGrrrl Posted July 28, 2017 Share Posted July 28, 2017 Wide ratio transmissions like the 5 speed were (usually) only available with the Maxidyne engines. The Mack Maxidyne 6 came in 237, 285, 250, 275, 300, 335, and 370 HP denominations. IIRC the 335 and 370 were only available from 2001 to 2006. What is advertised as a "350" with a wide ratio 5 or 6 speed is usually a 300 or lesser engine.
