I checked on pistons and liners for both engines and they where about the same . the LDS pistons have less rings then the old ones so maybe they have less compression = less power .maybe the military wanted this because the 5 ton LDS engine when rebuilt it would go back in a m35 and not a 5 ton I don't really know . I want a engine that has better power then I had and maybe I will get a little better fuel mileage . You are so right about the true shape of the new engine I will be pulling the pans and checking the bearings .

I pulled the fly wheel and bell housing off of the Mack ENDT 673 E today I noticed that the military bell housing holds the seal for the crank on the civilian engine it has a housing that holds the seal . I have to pull the pan next and check the main and rod bearings .

I pulled the oil pan on my ENDT 673 E I don't know what oil was used in this engine but it was very clean ( Rotella clean ) I pull a main and a rod cap both had bearings dated 8-98 they looked real good the crank looked very good . I noticed that this engine has no piston oilers .
