What people don't grasp is this. I can take an engine with a STONE STOCK cam. I can build it with more compression, a better induction and exhaust, a hot ignition curve and it WILL SOUND like a high performance engine, because it will be. It will simply perform in the RPM range the stock cam tells it to, but it will perform a LOT better. More compression added with "all that other stuff" I mentioned will have a huge influence on how the engine sounds. But getting people to understand that is an entirely different proposition.
