ODFL | merc. engines good thing or bad

as far as i know they only turned the speed up and not the horses i think thats what causes breakdown they tear thereself apart trying to pull 80,000 up hills
 
The Cat C-13 are set at 335, but they can go alway up to 525. My thinking is they should at least set them at 375. Mercedes motors are good for one thing-boat anchor.:chairshot:
