Engine Type Guide

Oversquare (bore > stroke): Higher RPM potential, favors horsepower. Common in sport and racing engines.

Undersquare (bore < stroke): More torque at lower RPM. Common in diesel and truck engines.

Square (bore ≈ stroke): Balanced power and torque. Common in modern street engines.

Frequently Asked Questions

Q

How do you calculate engine displacement?

Engine displacement equals (π/4) × bore² × stroke × number of cylinders. For a Chevy 350 with 4.000" bore, 3.480" stroke, and 8 cylinders: (π/4) × 16.0 × 3.48 × 8 = 349.8 cubic inches = 5,733 cc = 5.7L.

  • Formula: Displacement = (π/4) × bore² × stroke × cylinders
  • 1 cubic inch = 16.387 cc (conversion factor)
  • 1 liter = 1,000 cc = 61.024 cubic inches
  • Bore and stroke can be measured in inches or millimeters
  • Total displacement = single cylinder volume × number of cylinders

Q

What is bore/stroke ratio and why does it matter?

Bore/stroke ratio is the bore diameter divided by the stroke length. Oversquare engines (ratio >1.0) rev higher and favor horsepower. Undersquare engines (ratio <1.0) produce more low-end torque. Most modern street engines are near-square for balanced performance.

  • Oversquare (>1.0): larger bore than stroke, higher RPM, more HP (sport/race engines)
  • Square (≈1.0): bore equals stroke, balanced torque and power
  • Undersquare (<1.0): longer stroke than bore, more torque at low RPM (diesel/truck)
  • Ferrari F136: ratio 1.13 (extremely oversquare, 8,500 RPM redline)
  • Cummins 6BT: ratio 0.87 (undersquare, massive low-end torque)

Q

How do I convert between cubic inches, CC, and liters?

Multiply cubic inches by 16.387 to get CC, then divide by 1,000 for liters. A 350 cubic inch engine = 5,735 cc = 5.7 liters. Going the other way, divide CC by 16.387 to get cubic inches.

  • Cubic inches to CC: multiply by 16.387
  • CC to liters: divide by 1,000
  • Cubic inches to liters: multiply by 0.016387
  • Liters to cubic inches: multiply by 61.024
  • Example: 2.0L = 2,000 cc = 122 cubic inches

Q

What is the difference between displacement and total engine volume?

Displacement measures only the swept volume of the pistons (bore × stroke). Total engine volume includes displacement plus the combustion chamber (clearance) volume. The compression ratio relates the two: CR = (displacement + clearance) / clearance.

  • Displacement: swept volume of all pistons combined
  • Clearance volume: space above piston at top dead center (combustion chamber)
  • Total volume: displacement + clearance volume
  • Higher displacement generally means more power potential
  • Turbocharged engines produce more power per liter than naturally aspirated

Example Calculations

Result

Displacement5.7L (349.8 ci)
CC5,733
Bore/Stroke1.149 (oversquare)
Per Cylinder716.6 cc

(π/4) × 4.000² × 3.480 × 8 = 349.8 ci × 16.387 = 5,733 cc = 5.7L. The 1.149 bore/stroke ratio makes this an oversquare engine that favors RPM.

Result

Displacement2.4L (143.6 ci)
CC2,354
Bore/Stroke0.879 (undersquare)
Per Cylinder588.5 cc

(π/4) × 3.425² × 3.898 × 4 = 143.6 ci = 2,354 cc. The long stroke (undersquare) gives strong mid-range torque, popular for both street and boosted applications.

3Ford Coyote 5.0L V8

Inputs

Bore3.630 inches
Stroke3.650 inches
Cylinders8

Result

Displacement5.0L (302.1 ci)
CC4,951
Bore/Stroke0.995 (near-square)
Per Cylinder618.8 cc

(π/4) × 3.630² × 3.650 × 8 = 302.1 ci = 4,951 cc. The nearly square bore/stroke gives a balanced power band from idle to 7,500+ RPM.

Formulas Used

Engine Displacement

Displacement = (π/4) × Bore² × Stroke × Cylinders

Calculates total swept volume from bore diameter, piston stroke, and cylinder count. Result is in cubic inches if inputs are in inches, or cc if inputs are in mm.

Where:

Bore= Cylinder bore diameter (inches or mm)
Stroke= Piston stroke length (inches or mm)
Cylinders= Number of cylinders (1–16)
π/4= 0.7854 — converts bore diameter to cross-sectional area

Unit Conversion

CC = Cubic Inches × 16.387; Liters = CC / 1000

Converts between cubic inches, cubic centimeters, and liters for engine displacement.

Where:

16.387= Cubic centimeters per cubic inch
1000= Cubic centimeters per liter
