You know you’re going diesel for your next rig, and chances are you probably already have a pretty strong affinity for either Chevy or Ford. However, in the name of fairness and injecting a little variety into your life, find out just who comes out on top in the Chevy vs. Ford Wars: Diesel Edition. You might be surprised by some of the perks one make offers over another—and it might just be enough to lure you over the fence to the other side.
Even before dipping into the performance side of things, consider that Isuzu makes Chevy diesel trucks and Ford makes Ford trucks. Take that information and interpret it how you will, but some “purists” think this is a sign that Ford is the winner already—but not so fast. There are so many other considerations, like block and head materials as well as battery configuration.
Pop the Hood
When it comes to cylinder configuration, it’s a clear tie: Both vehicles boast a 90-degree V8 engine. Both make their head material out of aluminum, too, and this race is closer than anyone expected. However, things get shaken up a bit with the block material. Ford opts for compacted graphite iron while Chevy goes for cast iron. According to some, compacted graphite iron is stronger than cast iron, but of course, cast iron is a more classic (and proven) material.
With injection type, both Chevy and Ford use a Bosch Common Rail system (29,000 psi), making the race even more neck and neck. And that valve configuration? Both feature OHV 4 valves per cylinder. What about battery configuration? Chevy has a single 730 CCA battery while Ford ponies up a Dual 12-volt 750 CCA battery.
Pushing the Limits
The max torque reported for Ford is 677 with a max horsepower of 333. Chevy ups the ante with 671 max torque, but 360 horses. The most heavy duty of Fords, the F350, can haul 22,700 pounds with a fifth wheel and the Chevy Silverado 3500HD can carry an astounding 23,000 pounds with a fifth wheel. However, Ford offers a range of gear options while Chevy only has the 3.73 gear ratio available.
With engine displacement, Ford offers a 6.7-liter power stroke and Chevy is right on their heels with a 6.6-liter power stroke. Complete with a 3.9-inch bore for Chevy and a 4.06-inch bore for Ford, the engine comparison is really too close to call. For some, the stroke makes all the difference, and Ford offers 4.25 inches at a 16.2:1 ratio while Chevy has 3.9 inches and a 16.8:1 ratio.
Which one is the winner? As you can see, each one reigns supreme in different areas, so it really depends on personal preference, what you’ll be using your rig for and just how much hauling will be done. No matter which direction you head, keep in mind that a great way to up performance is to install a performance air filter or cold air intake—both of which will give your diesel engine the extra oxygen it craves.
