I've seen/heard about that before, I think it was in discussions here and I believe also mentioned in one or another of the old Hugh (edit: Herb) Adams, Greenwood or Chevy Power Manual papers. It is to reduce front end dive on hard braking & rear end squat on acceleration and thus handling problems due to weight transfer & suspension geometry changes, etc. It is done not to lower the car, but to correct the T-arm angle when the car has been lowered. It is a similar and complementary mod to raising the diff to correct strut rod (edit: I mean axle) angles.
