Question on a 60 series 12.7

Info on Gliders:
KW, they only offer Paccar, Cummins, and not sure if they still offer the Cat option or not.
Freightliner: you can spec to Cummins (just about any model...N-14, M11, etc), Detroit (14L,12.7, or 11.1L), Cat
Western Star: same as freightliner.
International: I know Cummins and their Navistar

I build gliders.....I hope after 40 of these I know a little! If you want Detroit......build a Freightshaker! Im doing CL120's with Detroits and N-14's

 

Fitzgerald has w900's in stock right now. Go get you one that comes standard with a 12.7. Borg Warner ported and coated manifold. The big turbo. And 500 HP of awesome fuel milage!
