7.3 power stroke VS. 6.4 power stroke engines: which one to choose for your truck

Ford brought the power stroke engines along with the Navistar company in late eighteen. Back then, the first member of the power stroke engines, the 7.3 power stroke, was the most popular among all the similar V8 or V10 engines for the sleek design and efficiency. It was one of the best choices for the lightweight trucks, minivans, and sports facilities pick-up vans. Soon enough, it took over the market. The Ford F could not reign the market with the 7.3 power stroke engine version for long due to some troubleshooting issues. The oil and water chamber interruption was one of these. Later on, Ford returned to the market with their new and improved six Powerstroke engine series versions. Here in this article, we will discuss these two generations’ efficiency levels and which one to choose for your trucks. 

Power stroke Generation

7.3 power stroke

The 7.3 power stroke came first in line with a single slot, direct-injection system. It is fully electrical and produces up to 256 horsepower and 425 pounds of torque per unit space. It became the reliable engine choice for the light to medium weight engines very quickly and was the top in the market back then. But, the fuel leakage started to take a toll on the Reputation, and failure to meet the California sound emission clause brought the production to and ended around 2003.

6 Generation Power stroke

After Ford stopped producing the 7.3 power stroke engines, they came up with the 6.0 power stroke engine series. Though soon after the launch, the engines started showing an even worse head gasket, cracks in the EGR cooler section, EGR failure, and bad injectors. That market went rough soon enough, and Ford had to close the production of 6.0 power stroke engines. 

6.4 power stroke

After the 6.0 power stroke engines’ heated disruption, Ford developed the technique, upgraded the designs, and brought the most effective 6.4 power stroke engines in the market. Though it was the last collaboration of Ford and Navistar, the machines could reign the need for more or less nine years. The 6.4 power stroke engines produce three hundred and fifty horsepower and more than six hundred torque per square unit. The sister design of the 6.4 was the 6.7 power stroke. But, this design also had some engine and hardware failure issues. So, 6.4 remained the best power stroke for Ford to date. 

One of the best features of the 6.4 power stroke is its bed plates. The bedplates directly attach the iron blocks eliminating the traditional bearing caps, and the 6.4 power stroke ebp sensor is another fantastic addition to the series. The EBP Stands for the exhaust backpressure. It saves the engines and turbochargers from overheating and prevents the excess formation of diesel particulates. It also reduces the time for the machines to reach the desired temperature by restricting the exhaust flow. The sensor will also increase the engine load to ensure fast thrust. 

Conclusion

The connecting rods are the strongest and the weakest part at the same time for the 6.4 power stroke engines. It can take up to 900 horsepower energy and more than 1500 torque per square unit area. It’s impressive for any lightweight truck and vehicle. But, at the same time, the head links are the weakest part of the block. So, as a result of the comparison, the 6.4 power stroke engines stand out all.
