We have a fleet of internationals n I've drove and done minor work on them but from what I've seen there not all that special they bog down hauling near about anything an older mack we got has a higher top end and it just rides better am I bias or is the international just a piece of crap everyone we got is less than 1-2 years old??

Doesnt International put DD15s in their trucks, no?

If so there really isn't a better diesel motor lol

Ours have cats in it n there nice but I guess I prefer the macks

Cat and cummins both make good power.

You can keep that detriot bullshit. Loud, no-power having scrap iron.

Fuck that. We used to have a fleet of older double barrel 12v71 scrapers and all they did was make noise.

Drove one of the brand brand new ones today it rode nice clutch was great plenty of power I just think the others need tune ups or something the difference in them was a lot guess cause no one has WORE it out yet lol

detroit 60s are great motors. i have a c15 cat now and its turned up and i love it. also different motors have different powerbands this c15 seems to like higher rpm running while the cummins isx i used to drive seemed to have better power at lower rpms. theres so many variables really you cant just be generic and say these internationals dont run worth a shit.
