...most diesels are low-rpm (compared to SI-engines), where LONG strokes are used to capture & maintain more "flywheel" affect...maximization of torque.

...the faster you want the engine to turn, the SHORTER the strong typically needs to be...of course, at the expense of some amount of torque.

...the REAL question, however, is "...how strong..." is the block because of the MUCH greater cylinderwall pressure of a diesel (20-22:1 CR) over gasoline (8-10:1 CR).
