Powerstroke vs Duramax vs Cummins

Are you looking to buy a new truck because there are a lot of good ones out there but you have to make sure you pick the right ones for your need. The three main trucks people talk about are Chevy, Ford and Dodge all American. Chevy owns the Duramax engine, Ford has the Powerstroke and Dodge has the Cummins which are all great engine but just with a little difference. Now I'm comparing the top engines in these trucks. Dodge and Ford have both Iron engine blocks while the Chevy has Iron Aluminum and what the means is you're going to get the same about about power but with a smaller and lighter engine. Which equals you being able to use the power towards pulling instead of just moving your own truck. Just that alone subtracted around 300 pounds off the engine which will help you in the long run. All engines are around the same size which is 6.6 liters or about 400 cubic inches only differences is the Dodge has 6 cylinders and the rest has 8. All three comes with a turbocharger the Ford comes with two. Most diesel engines  has one and what that does is force more air into the engine block so give the truck more horsepower and torque. The Chevy is rated at 365 hp and 660 lb-ft at 1800 rpm while the other are 350 hp and 650 lb-ft but the Dodge can reach this at 1500 rpm which would mean it works last as hard to get the same power because it doesn't have to spin as fast. To me I would go with the Chevy because it's lighter and produces more power at only 300 rpm and also backed by a Allison Transmission.
