(Bob Spidell remarked that his '67 A/H 3000 understeers badly, suspected
high front weight bias, and asked about fudging tire pressures.)

    Actually, despite that 600 lb chunk of iron up front, the big A/H
balances out at 49% front/51% rear balance (it must be all the lead
in the boot-mounted battery :) ).  Some understeer is a natural byproduct
of the single, front anti-sway bar;  by stiffening the front roll action,
greater load is put on the outside front tire in a turn, causing it
to slip more than it would without a swaybar.  Increasing the front
tire pressures (or decreasing the rears) would decrease the front slip
angle (increase the rear) and reduce your understeer.  If you think
your understeer is a symptom of something awry, look at the shock absorbers;
I believe weak rear shocks would cause initial understeer like you describe.
