Chevrolet 134ci specs: 134 ci (2.2L) 4-cylinder, 3.50 x 3.46 in (88.9 x 87.9 mm) bore and stroke, 9:1 compression. Rated 115 hp, 2001–2002. OHV.
The Chevrolet 134ci is close to square: 3.5" bore against 3.46" stroke, within 1.2%, which splits the difference between a high-revving layout and a torque layout. 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. Each of the 4 cylinders displaces 33.5 ci (549 cc).
9:1 on iron heads is low by modern standards and generally happy on regular pump fuel.
