Welcome to International Power stroke, a website built for Power Stroke Diesel Enthusiasts, by Power Stroke Diesel enthusiasts. Here, you will find 7.3, 6.0, and 6.4 liter Powerstroke Diesel specifications, history, and general information. The PowerStroke Diesel engine has by far been the most popular & sought after diesel on the light duty market.

General PowerStroke Information:

Why A V-8?

When designing the first diesel engine for Ford trucks, International wanted an engine that would make the truck versatile, as both a work horse and reliable daily driven vehicle. After all, it was unlikely that a trailer would be permanently hitched to all these trucks and towing be their sole purpose. Therefore, a V-8 configuration was chosen. The prefered V-8 gave the trucks plenty of low RPM torque for towing, and built horsepower throughout the RPM range for better daily driver performance. In comparison, an inline 6 cylinder diesel would peak out at a low RPM and lower performance in the high RPM range, hardly desirable for such a versatile pickup. The V-8 has proven to be the most popular design in a light duty diesel truck.

What Engine Evolved Into the Power Stroke Diesel?

The International engine that started it all was the 6.9 IDI. The indirect injection 6.9 was simple in design, naturally aspirated, made 170 hp @ 3300 RPM, and 315 lb-ft of torque @ 1400 RPM. The 6.9 was released in 1983 and gained instant popularity. So much in fact, that Ford had to ask International to increase production of the engines, a move that produced a great stream of revenue for both companies. Sometime in 1987, the bore of the 6.9 was increased from 4.00 in to 4.11 inches, and the 7.3 IDI was born. It was in 1994 that the 7.3 IDI became a direct injected, turbocharged diesel and proudly named, the "Power Stroke".

Which Power Stroke Is Considered The Best?

That is a difficult question to answer and is best left to personal opinion. Without doubt, the 7.3 liter PowerStroke has been the most popular. Its time proven durability, reliability, and all around performance have given it a great reputation. However, both the 6.0 and 6.4 liter Power Stroke's feature higher power output and advanced technology. So, in order to answer this question, I ask in return...Do you prefer displacement (7.3), fuel mileage (6.0), or twin turbo performance (6.4)? It really is a matter of preference...Truth be told, you just can not go wrong with a PowerStroke!
