Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION
Cams are picked for purpose. The purpose is determined by the owner/builder. Some to create low end torque, or to pull past 6000 rpms, or gas mileage, or just for sound. Yes, some folks really don't care if they get the ultimate performance, they just want the cool sound. In fact, there is such a demand for it (sound) that companies compete in the Thumper/Whiplash market.
Some miss their goal to meet their purpose due to mismatch components, or shall I say not getting the right cam for the rest of the engine and drive train.
Ironically, the most purposed cam sold giving the most smiles are the thumper/whiplash cams. Those who only purpose for sound are usually happy when the hear their thumper idle. Utube is full of smiling examples.
