help with choosing a 379

Cats suck. They're heavy and they're expensive to fix

 

My 99 has a Detroit, cats get in my way.

 

I beg the differ CAT is the only thing I'd own solid motors in that time frame ​

 

Even with a tired CAT with a million miles I walked by broke down Detroit's and ISX trucks all the time.

Now my CAT is getting a refresher...

 

get one with a 2ws 3406e

 

That's a good year range for pretty much any engine brand. The electronics had been around long enough to get a lot of the bugs worked out and there isn't any EGR and DPF crap to worry about. 2003 was pretty much the beginning of the end for engine reliability IMO.

 

2ws,6nz, mbn are the popular ones. But don't be afraid of 5ek,6ts or 1lw serial # cat engines. Built right they will be trouble free for miles and miles.

 

Also 5ds,1mm or 7cz are the muscle motors. But are rare to find.
