heh I learn something everyday I heard aftermarket cams sounds nice. But Im kinda newb in that subject about cams.
all a camshaft does is open and lose the valves---there is what is called lift and duration of the cam lobe(the part that pushes the valve open)----lift is how high the valve opens and duration is how long the valve stays open----
that is why you need better heads and such with a larger cam-----if a cam stays open longer or opens more to let more air in----you have to have a head that will let that extra air in as well------
