The shorter upper arm derives from the time when control arms were almost always parallel to the ground. At the time of the "birth" of independent front suspension, it was conventional wisdom that the roll center had to be at ground level. With narrow tires and high center of gravity, the angle of the contact patch wasn't that important with narrow tires anyway.
So... the short/long control arm design was created to keep the position of the contact patch in a straight vertical line under bump and rebound. The tire tilts in going up - and also tilts in going down.
Things have changed a bit since.
If you want to see some "interesting" contact patch movement, analyze a McPherson/Chapman strut.
But - most of them survive quite well by having very long LCAs.
At any rate, to
your problem! It sounds like both of your arms are angled much too much. They will put the roll center below ground, and you want it slightly above ground. Since you already have ball joint bind, that's a good enough excuse to change pivot points already. A few more details
here.
Is it necessary to have 1" chassis rake?
