P.S. The sliding sleeve thermostat that I installed only helps
marginally.  The temp here is SoCal is in the 90s today and the water
temp went to 212F after 15-20 minutes of driving on the freeway today.
We checked the timing today with a timing light and it was right on.  I have a 
3 row radiator.  I give up.
Mike,
Just one thought.  If that 3 rows radiator is louvered instead of staggered 
core, that might be the problem.  3 row staggered cores are significantly more 
effective/efficient than the louvered fin design.  Are you sure the carb isn't 
leaning out on you with the supercharger?
Mike
