with some new SD46-3 (sd45-2 upgrades), these engines do have good specs, not as good as the GFMD SD46T-3S (https://www.furaffinity.net/view/57322272/), but they still keep the ordinary SD40-2 look while being the only -3 to have a 20 cylinder 645, and with more canadian specs, even tho they are supposed to be the desert runners, they run in the cold winter of canada!
