Hemi
- Hemispherical combustion chambers
- Shorter, straighter intake and exhaust ports
- Larger valves
- Higher compression ratio
Regular V8
- Non-hemispherical combustion chambers
- Longer, curved intake and exhaust ports
- Smaller valves
- Lower compression ratio
Performance
These design differences give the hemi engine several advantages over the regular V8 engine. Hemis typically produce more power and torque, and they are more efficient.
In general, Hemi engines are more powerful and efficient than regular V8 engines. They are often used in high-performance cars and trucks.
