One thing I should have pointed out is that the specs I gave you were
the factory specs.
Back then the Corvette came equipped with bias-ply tires, not radials,
so most shops would probably use 1/16" total toe-in for the front wheel pair
(1/32 per side) rather than the factory spec of 1/8" total (1/16 per side).
I recommend you make that change to the spec I gave you.

Factory camber setting is intended for average boulevard/freeway driving.
From what I've read, a more spirited driver might prefer camber more in
the
negative direction from the stock positive setting, and perhaps a bit
more caster.
But now you're into trial & error until you get the "feel" you like for
the type of
hard driving you're doing (like slalom racing or whatever).

For example, these settings might be more suitable for an aggressive driver
(fast cornering), but are not all-out slalom race car settings:

 front:
  caster: 1 1/2 degrees positive
  camber: zero to negative 1/2 degree
   toe-in: 1/16 inch (1/32 per side)

 rear:
  camber: negative 1 degree
  toe-in: 1/16 inch (1/32 per side)

Ideally, alignment should be done with the car configured as it would be for
everyday driving, with weight added for the driver (and passenger, if there
normally is a passenger).... not many shops bother with that nicety, but
back in the 60's I worked briefly at the GM proving ground, and they
used such weights when they performed a scheduled alignment on any
of their endurance test cars, simulating the test driver, so obviously
their engineers thought it prudent. I can't recall whether they were
particular about the fuel load, though.
