Nissan Cummins ISV5.0 specs: 5.0L (305 ci) 8-cylinder, 94 x 90 mm (3.7008 x 3.5433 in) bore and stroke, 16.3:1 compression. Rated 310 hp, 2016–2019.
The Nissan Cummins ISV5.0 is close to square: 3.7008" bore against 3.5433" stroke, within 4.4%, which splits the difference between a high-revving layout and a torque layout. 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 8 cylinders displaces 38.1 ci (625 cc).
At 16.3:1 this is a compression-ignition engine: the ratio is the heat source that lights the fuel, not a knock limit to be managed.
4 factory variants share these dimensions, rated at 310 hp across 2016–2019.
