Ford CVH 1.9 HO specs: 114 ci (1.9L) 4-cylinder, 3.226 x 3.46 in (81.9 x 87.9 mm) bore and stroke, 9:1 compression. Rated 108-115 hp, 1986–1990.
The Ford CVH 1.9 HO is undersquare — the 3.46" stroke exceeds the 3.226" bore by 6.8% — a layout that trades peak RPM for leverage and torque low in the range. The 3.46" stroke puts mean piston speed at 4,000 ft/min around 6,950 RPM, which is where a production bottom end is generally considered at its limit. A rod ratio of 1.55 is short — higher piston acceleration and more side-load, typical of stroker combinations and a reason to watch piston speed closely. Each of the 4 cylinders displaces 28.5 ci (467 cc).
9:1 on iron heads is low by modern standards and generally happy on regular pump fuel.
It is one of 5 engines in the Ford 114ci family, all of them 114 ci — the differences between them are in compression, heads and rating, not displacement. 5 factory variants share these dimensions, rated from 108 to 115 hp across 1986–1990.
