Engine displacement from bore and stroke
Displacement is the swept volume of every cylinder — the space the piston travels from BDC to TDC.
CID = (π ÷ 4) × bore² × stroke × cylinders. Liters and cc follow from the cubic-inch total.
Overbores and stroker cranks both raise displacement; bore changes scale with the square of diameter.
Whether you are machining a small-block 0.030″ over, comparing an LS 5.3 to a Coyote 5.0 badge, or checking what a 3.750″ stroker does to a Windsor, this free engine displacement calculator turns bore, stroke, and cylinder count into cubic inches, liters, and cc instantly.
Defaults match classic SBC 350 territory — 4.00″ bore, 3.48″ stroke, eight cylinders — about 349.8 ci / 5.7 L. Use the preset chips for common crate and OEM geometries, then tweak to your finished bore and actual crank stroke.
Displacement alone does not set power or compression. Pair this tool with a compression ratio calculator when you change pistons or heads, and with a displacement converter when you only need liters ↔ cubic inches without the geometry math.
How to use the engine displacement calculator
Enter bore and stroke. Use finished cylinder bore and crank stroke in inches or millimeters.
Set cylinder count. V8 = 8, inline-four = 4, and so on — total CID multiplies by cylinder count.
Read CID, liters, and cc. Compare against crate badges or use a preset (SBC 350, LS 5.3, Coyote 5.0) as a starting point.
Engine displacement FAQ
Cubic inches = (π ÷ 4) × bore² × stroke × number of cylinders, with bore and stroke in inches. Liters ≈ CID × 0.016387064. This calculator also accepts bore and stroke in millimeters.
Marketing badges round. A classic SBC 350 is about 349.8 ci from a 4.00″ bore and 3.48″ stroke. Factory “5.3 L” and “5.0 L” names are similarly rounded versus exact geometry.
Yes. Displacement scales with bore squared, so a 0.030″ overbore on a small-block adds meaningful cubic inches. Re-run the calculator with the finished bore, not the stock casting size.
Close enough for shop talk. Exact conversion is 1 cubic inch = 16.387064 cc, so liters = CID × 0.016387064. This tool uses that factor for liters and cc.
Use the crank’s stroke (and the cylinder bore you actually machine to). Deck height and piston compression height matter for compression ratio, not for swept displacement.
