		The cam is the final piece  in the motor's combo, determined by the rest of the components. With stock heads, unmodified, a big duration race cam will begin to make it's power after the rest of your motor is out of it's operating RPM. What works in a completely different combo will not work the same in yours.  It took my four different cam grinds in my first hot rod to realize I had stock heads,  low compression (9.5:1), and a short block that wouldn't routinely handle 7200 RPM without breaking; before I listened to my machinest and got "that tiny cam" he recomended and had a faster car that was more fun to drive.  I learned the hard way, had I listened to my machinist....well I still might think bigger is better.
