I have a few questions about motors.
In over the road applications which motors are more reliable Detroit cat cummins Mack? For some reason I have been interested in big trucks and the performance aspect of it. To me it seems like most people would prefer a 6nz or c15 c18 over a isx or 60 series. Do they last longer,? More power?
