Which Emission Compliant Engines Are Worth It?

Negative. A Maxxfarce needs fixed from minute 1. Unless you enjoy spending days waiting in a shop driver lounge. Just do a simple search for used trucks and you'll find one make/model/engine will be listed with the lowest miles and lowest price. The same year/make/model truck with a cummins engine will nearly always have double the miles and have a 50% higher asking price.

Upping power can be done with the fix and usually is.

 

Buy an old truck with a series 60. It's the best route if you can find a decent one. The ones that have them hold onto them.

 

You don't want that w9 with the 6nz..... got a link to it?

I wouldn't run the maxforce for any amount. Side of road = unhappy customers or even load claims if a load spoils. I am happy so far with my 15 isx. Only 220548 km on it so far though. knock on wood

If you can bring yourself to buy a Volvo or a mack they seem to have the least problems overall, but then when they do the service network can be few and far between. Sort of a crap shoot any way you cut it.

 

Don't walk away from the max force. Run run run fast

 

As much as it pains me to say this the mack mp8 is about as good as it gets for emission motors.
