Chevrolet L52 specs: 211 ci (3.5L) 5-cylinder, 3.661 x 4.016 in (93 x 102 mm) bore and stroke, 10:1 compression. Rated 220 hp, 2004–2006.
The Chevrolet 214ci (L52) is undersquare — the 4.0157" stroke exceeds the 3.6614" bore by 8.8% — a layout that trades peak RPM for leverage and torque low in the range. The 4.0157" stroke puts mean piston speed at 4,000 ft/min around 6,000 RPM, which is where a production bottom end is generally considered at its limit. Each of the 5 cylinders displaces 42.2 ci (692 cc).
10:1 is in the range that usually runs on pump premium.
3 factory variants share these dimensions, rated at 220 hp across 2004–2006.
