Ford Triton SOHC 2V specs: 281 ci (4.6L) 8-cylinder, 3.551 x 3.543 in (90.2 x 90 mm) bore and stroke. Rated 225 hp, 1998–2014.
The Ford Triton SOHC 2V is close to square: 3.551" bore against 3.543" stroke, within 0.2%, which splits the difference between a high-revving layout and a torque layout. The 3.543" 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. A rod ratio of 1.675 is in the range most production engines fall in. Each of the 8 cylinders displaces 35.1 ci (576 cc).
It is one of 22 engines in the Ford 281ci family, all of them 281 ci — the differences between them are in compression, heads and rating, not displacement. 11 factory variants share these dimensions, rated at 225 hp across 1998–2014.
