Model a engine flows air at about 16o cubic feet per minute,stock a zenith flows at about 80 cfm,Stromberg 97/Holley 94 flows around 170 cfm.

See your engine as an air pump,use all the air it can pump creating useable atomized fuel.basically match cfm of carb to cfm of engine.doing this increases economy and power,the engine gains efficiency by using all its volumetric capacity to conduct useable fuel.

adding higher compression to the equation makes the combustion process more efficient,higher compression yields a faster more efficient burn.when you burn fuel at a higher efficiency rate your engine actually runs cooler.
