That is true... if going w/ a completely custom cam. I had Patrick G spec a new cam for me, but in the end I'm going to keep my G5-X2 in there. With an off the shelf cam you usualliy have the option of picking which LSA you want w/ the grind. The quick and dirty of it all is that the lower the LSA the narrower the power band and lower in the RPM range while the higher the LSA (wider angle) the broader the powerband is, but with peaking coming higher in the rpm range.
I don't disagree that for a street only car you want lots of low end torque. My car doesn't start to boogie until 3500rpms... it's no dog below that, but it could have more grunt. The nice thing is that w/ my wide duration spread the cam makes great power after peak and will pull past 7000 rpms easily if I wanted to. However I only pull it to 6800ish on the street.
