2 stick ... the A models from what I understood they were more costly to rebuild because of the one piece head .... if it was cracked or otherwise OUCH ! .....but what an awesome engine ......
My truck had a Big Cam 475 twin turbo when I first got it .... Loved the power nice to drive ...BUT ..... in 9 years, 39 injectors, 2 major fuel pump rebuilds, 4 water pumps, 12 pistons and liners ( cracking and electrolocis), and every year wether I wanted to or not $2,500.00 tune job including the jake spools set-up and valves set and the MVT re-built, 2 sets of turbos (ouch) and cracked cam followers needing a rebuild ....the final straw was it cooked its self when a liner went ..... in my second truck almost a twin to the first for specs, it had about the same amount of hrs and milage ...it was powered with a 425B model cat, it had none of the above issues like the Cummins, one bearing roll-in (prev.maintainance) it found its way into my first Truck which is another long story how/why ....but not now .....CAT all the way
