        I'm not sure about the 80% part but I did see an explanation about
shift points.

        You need to look at your engine's Torque Curve and you need to know
what the RPM change is for each of your transmission gears.  The idea was to
shift at an RPM after peak torque that would bring you to that same torque
value before peak torque.  This uses the Max Torque of the engine to propel
the car.  This seems to make sense but I do not know if will get you down
the track any faster.  I have never drag raced, only short bursts on the
street, so I'm no expert.

Bob, interesting point on the shift points.  I understand having the
revs in the sweet spot, but how did the 80% come about.

If I have the stock motor and cam from the 90 5.0L, and its max hp is at
5200 rpm, the the shift point is 6500 rpm.  That is quit a jump, and
with stock valve train, mainly springs, I am sure that valve float would
 become a problem.
