Horsepower of a car....a bigger engine has less horsepower?

Horsepower at rpm (xxx@xxxxrpm) means the maximum generated power of the engine at that rpm(revolutions per minute) Horsepower is really a silly way of measuring power imo. If either engines from chevy or pontiac was to produce power and be equally efficient at the same rpm as the honda than I'm sure their numbers would be a tad bit closer. I think the other two designed their engines for low end grunt and in turn sacrificed a longer powerband to produce power at higher rpms. There's trade offs for everything so I wouldn't jump to the conclusion that 1 is better then the other. Don't base you assumptions on peak numbers. Of course maximum generated power revolves around too many variables. Look up volumetric efficiency and study up on your chemistry.
