Compression, is on part of the internal combustion cycle that add torque to the crankshaft. Compression and displacement is the key to a great street engine. When the L-100 can became the go to cam for a street engine. It did so at the cost of low speed torque. So I and others, added displacement to the brew anr revived most of the low speed torque. After 2500 rpm the cam improves the torque curve with better breathing. But it was the sound that sold it. So when building an engine for the street, compression is your best friend.
