Engine Design Characteristics
Oversquare (Bore > Stroke)
- • Higher RPM capability
- • Better breathing at high RPM
- • More valve area per displacement
- • Example: Ford 302 (4.00" × 3.00")
Square (Bore = Stroke)
- • Balanced design
- • Good all-around performance
- • Moderate RPM capability
- • Versatile for many applications
Undersquare (Stroke > Bore)
- • Higher torque production
- • Better low-end power
- • Longer connecting rods possible
- • Example: Pontiac 455 (4.15" × 4.21")
How to Use
