The 7.3 Powerstroke has a HEUI-hydraulically actuated electronic unit injection-fuel injection system. This is not to be confused with overall capacity, which I detail in that 7.3 oil change article. I talk about this in-depth in the 7.3 oil change article, but the 7.3’s oil change capacity was and remains 15 quarts. 7.3 Powerstroke Engine Dimensions SpecĪnd the dimensions of the 7.3 L diesel are 34″Lx32″Wx38″H 7.3 Powerstroke Compression Ratio Spec The 7.3 Powerstroke displaces 444 cubic inches-7.3 liters. 7.3 Powerstroke Bore and Stroke SpecĤ.11 in (104 mm) bore and 4.18 in (106 mm) stroke 7.3 Powerstroke Displacement Spec If you have trouble keeping the details of those two straight, just remember that horsepower’s for hauling ass. And the amount of torque that an engine can exert depends on engine RPMs. In your 7.3 Powerstroke’s case, actually in any diesel truck, it’s the measure of rotational effort applied on a diesel engine’s crankshaft by the pistons. Torque is “a twisting force that tends to cause rotation.” Or simply, twisting force. 7.3 Torque Specs – DefinedĪnd let’s continue to make sure we’re all speaking the same language. Today, that unit of measure is used to define how powerful an engine is. Now, let’s revisit what horsepower means – a unit of power equal to 550 foot-pounds per second (745.7 watts). Impressive!įord continued production runs of the 7.3 Powerstroke diesel until mid 2003 when, sadly for us enthusiasts, emissions requirements caused them to cancel production and replace the 7.3 Powerstroke with the “less-than-bulletproof” 6.0L Powerstroke.īut that’s another story… 7.3 Horsepower Specs – Defined These and other factors made the engine awesome for its time! And over twenty years later there are still reportedly over two million 7.3 Powerstrokes still on the road today. The block and heads on the 7.3 Powerstroke were made of cast iron, making them tougher and longer lasting.Īnd Ford’s 7.3L powerstroke diesel was equipped with two overhead valves for each cylinder. And after that Ford released their first vision of that Navistar 7.3L diesel V8 engine in 1994. You may not know that Navistar-International-originally built the 7.3L diesel V8 engine-the T444E turbo-diesel. When you buy through links on our site, we may earn an affiliate commission.
