HP is a function of how much air-fuel mixture the engine will pump through it per hour. Take the 350 Chev for example with small high velocity ports, 76cc combustion chambers and a short duration cam. It will make lots of low rpm torque but mid range and peak HP will be limited. Take the same 350 shortblock with a set of Edelbrock RPM heads with 64 cc chambers and a high lift/long duration cam. Peak torque may be even equal to or even greater than the previous low speed engine's version. How ever the peak torque will occur at a higher rpm. Of course max HP will be greater and occur at higher rpms. Fuel consumption per HP per hr of the engines could be identical. Every body thinks a 400HP engine uses a lot more fuel than a 200HP engine.Well yes it does but everybody forgets the 400HP engine is performing twice the work per hour.
