Everybody knows the story of The Little Engine That Could. “I think I can…I think I can…I think I can!” the Little Engine repeats to itself as it tries to climb the mountain while pulling the load. It’s a great teaching tool for young children to give something a shot even if it seems difficult, because you don’t know just what you’re capable of until you test yourself, right? Well, meet the GMC Astro that will. It will pull this sled all the way down the track, and it’ll do it with the wheels in the air because they aren’t needed. It will let it’s 8V72 sing the song of the two-stroke diesel at the top of it’s lungs. It will dig deep and make yanking all of this weight look easy. And it’ll leave a sheen of sweat on the brow of every old-school trucker who remembers when automatic transmissions, cruise control and an apartment on the back of the cab weren’t the standard, but the ability to put over a thousand foot-pounds of torque to work was a daily tasking that put bread on the table. Your Kenworth might be more comfortable, but with a couple of exceptions to the rule (a few that Lohnes knows personally come to mind), chances are good that your over-the-road hauler isn’t going to put up this kind of fight against weight for quite some time…if ever.
No such thing as a 8V72.
It’s either an 8V71 or an 8V92.
Been into a few that were wore out enough to be 8V72s lol
