Ford 3.0L Power Stroke specs: 182.6 ci (3.0L) 6-cylinder, 3.307 x 3.543 in (84 x 90 mm) bore and stroke, 16:1 compression. Rated 250 hp, 2018–2021.
The Ford 3.0L Power Stroke is undersquare — the 3.5433" stroke exceeds the 3.3071" bore by 6.7% — a layout that trades peak RPM for leverage and torque low in the range. The 3.5433" stroke puts mean piston speed at 4,000 ft/min around 6,750 RPM, which is where a production bottom end is generally considered at its limit. Each of the 6 cylinders displaces 30.4 ci (499 cc).
At 16:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
It is one of 2 engines in the 3.0 Power Stroke V6 family, all of them 182.6 ci — the differences between them are in compression, heads and rating, not displacement. 4 factory variants share these dimensions, rated at 250 hp across 2018–2021.

| Bore/stroke character | 0.933 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,543 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 30.4 ci |
| Static compression | 16:1 — high enough that pump premium or better is normally required |
