Rumored 'Big-Block' Duramax Diesel Could Be 8.3L and We’re Off the Rails Now
You'd expect diesel engines to get smaller as time goes on, but recent reports claim GM's truck power plant could grow by more than a liter.
But now that people are still talking about the so-called "big-block" Duramax, I feel like it's time to acknowledge the possibility, however scant, that we might get a new diesel pickup engine with 8.3 liters of displacement. General Motors hasn't confirmed that the Duramax will grow in size, but TFL's source says it could be an 8.3-liter lump making as much as 600 horsepower and more than 1,200 pound-feet of torque. If you didn't know, Banks is a supplier of Duramax-based engines to the US Army for its Joint Light Tactical Vehicle program, so they also have a special interest in this particular diesel power plant.
