516 replacing 426

Soooooooo any update on this?

My argument is if the 516 is such a poor engine and outdated then why, praytell, did Allis put it in the N7? And why is it considered a better engine than the N6's 426 by most combine operators? My dad's HD11 has the 516 and it is a great starting engine even in the cold and is very fuel efficient compared to the neighbors Cat, going by the Cat owner who used to own that very HD11. I've seen testimonials on the combine forum where most with experience with Gleaners of that vintage say the 516 is a far better engine than the 426 and actually uses less fuel in the N7 than the 426 in the N6. I have never bought it that it was an obsolete engine. You know what? If it needed upgrades like a better fuel system or better piston design or whatnot then do that. If there is too many cast Iron parts....oil pan? or valve covers? I don't what is cast on these......... Put tin on. I don't get it. The engines used by Case are big and heavy and that is used as a selling point. And anyhow, a 7080 needs 1500# of weight added out front and fluid in the front tires in order to use the power. Skip some of that by using a heavier engine. Tell me this, how well did an over reved 426 putting out 220 flywheel HP work out? Thought so. Hindsight is 20/20 but my hindsight says the 516 would have been a far better choice and the warranty work that Allis was forced to spend big dollars would have been avoided not to mention the reputation the 7580 and 7080 gave Allis that affected the whole line by rumor. There................ rant over. I'll take a biscuit.
