Cummins ISB6.7 Engine - Pros and Cons?
Hi Everyone! Eyeing up a full length 70 seater 2011 Freightliner / Bluebird C2 that is powered by the Cummins ISB6.7 engine with an Allison 2500 Transmission.
Not familiar with this powertrain, so I thought I would get some feedback from the experts on here. What are the Pros and Cons?
Thanks in advance for your feedback!
