2002-2007 Mack engine question

[GVES]

I am wanting to buy or build a Mack dump truck.  What are the best and worst engines from 2002 to 2007?  I know to stay away from 2004 AC engines. 

I'd like a 2005-2007 Granite with 256" wheelbase and 44,000 lb. camelback suspension.  I would add a steerable pusher axle and an Ox Stampede demolition dump body.

AI internal engines are best from 2002 to 2007. Minimal electronics, no VGT turbo or EGR cooler, in general fairly reliable. Since it's a dump truck I think it's the only option as the AC cooled EGR engines only came in highway trucks. All vocational were AI.
