6.4 Powerstroke Vs 6.7 Cummins

Compared to their counterparts, the 6.5 and 6.7 Powerstroke diesel engines both produce approximately 400 hp and can tow up to 19,000 pounds. However, while the 6.4 Powerstroke is more fuel efficient, the 6.7 is far more powerful. While the 6.5 Cummins has more horsepower and torque than the 6.4, it is less reliable than its older counterpart. Here is a comparison between these two engines.

The 6.7L Powerstroke uses cast-aluminum heads and a bed-plate on the bottom end. In comparison, the 6.4L uses a CP4.2 high-pressure fuel pump, which can only flow 650-700 rwhp before failing. The 6.6L features a K16 high-pressure fuel pump and four 16-mm head bolts per cylinder.

The 6.4L Powerstroke’s design was primarily for throwaway trucks, and it was hard to maintain. Basic services required removing the cab. Due to the difficulty of maintaining a 6.4L engine, Ford abandoned Navistar and developed its own powerstroke engine. The 6.5L and 6.6 Powerstroke are very similar, but they are designed by two different companies. For this reason, the 6.5L is much stronger and lightweight.

The 6.7L Cummins is more reliable and cheaper. The 6.4L Powerstroke lacks technology and reliability features that would raise the cost of manufacturing and maintenance. Nevertheless, it may be more expensive to maintain than the 6.7L Powerstroke because of the possibility of problems. The 6.6L Cummins is more expensive than its 6.4L counterpart, but the former has less maintenance costs and more fuel economy.

Although both diesel engines are very similar, the 6.7 Powerstroke is more reliable and cheaper, which is why it is preferred by many truck owners. On the other hand, the 6.4 Powerstroke has several disadvantages. The latter is harder to maintain, and it needs to be disassembled completely before basic repairs can be made. The cab must be removed from the truck to get repairs. The 6.5 Powerstroke’s lack of a bed-plate makes it less likely to be reassembled and serviced, and the head bolts have fewer bolts than the 6.5.

The 6.7 Powerstroke is not an easy engine to maintain. The 6.4 Powerstroke is easier to work on and has a bed-plate on the bottom. The 6.7 Cummins does not have a bed-plate on the bottom. Its engine has four 16mm bolts on each cylinder, while the 6.4 uses four head bolts. It has a more robust and durable cab, but still has many disadvantages.

The 6.4L Powerstroke is easier to maintain. The 6.7 Powerstroke’s cab is easier to remove. The 6.6L Powerstroke also has a larger bed-plate than the 6.4L. The 6.6L Ford Powerstroke is a little heavier, but the 5.7L is more powerful. Its 6.2L is more popular than the 6.7 and has better torque.

The 6.4L Powerstroke is easier to maintain, but it requires more maintenance. Its connecting rods are a quarter inch bigger than the 6.7 Powerstroke’s. The 6.5L Powerstroke has a higher compression ratio, while the 6.4 has a larger bed-plate. The 6.6L is not a hybrid; it has four 16mm head bolts per cylinder.

The 6.7L Powerstroke is a bit more powerful than the 6.4L, but it’s also more expensive. The 6.5L is more powerful than the 6.4, but it is not as durable as the 6.6. The 6.6L also has a larger bed-plate and is less efficient. Nonetheless, it’s still a solid choice. It’s also easier to maintain.

The 6.6L has a better EGR system than the 6.4L. It uses two EGR coolers, and the 6.4L uses one. Despite their similarity, they do not share the same 6.0L’s bed plate. The 6.7L’s is equipped with four EGR valves. The 7.0L uses a hot-side EGR valve that prevents soot buildup.

The 6.4 Powerstroke uses diesel, while the 6.7 Cummins uses natural gas. The 6.6 Cummins is more fuel-efficient, with a 17-mpg average. Hence, it’s not always better for performance. On the other hand, the 6.7 Powerstroke is designed for heavy-duty trucks. It’s a powerful engine, but its hefty size limits its usability.
