Bruce,
you are very much right...
easiest to look at a torque curve...
no matter what cam timing, to a limited extent, camshaft, and many of the
other tuning tricks available..the AREA under the curve will generally be
the same..advancing the camshaft, will move the peak downward, smaller
intake plenum, moves it upward, these are all compromises..moving torque
from one place to another in the curve...the stock cam timing is a little
retared, IMHO, but at speed..(80 or so) you are well into the
curve....advance it and you lose torque at the high end...etc...
