What does a more aggressive cam do?
A more aggressive cam will change the way the valves to open and close in a manner to facilitate more air flow, but you need the intake and exhaust side up to snuff to benefit from it. The cam also needs to be profiled to augment the engine setup, not hurt it.9 Dec 2012
