Chris,
It is always a good idea to have a temperature probe to help calibrate your
gauge and sending unit so you can diagnose possible defective sender or
gauge. I would suggest that you make friends with a good radiator shop and
ask them if you can't get the car hot and then bring it in to them and let
them probe the car. Most of the better shops (even some smaller normal
garages,) have a hand-held gun like device they can point to various spots
on the car and get readings for hot spots.
When I re-did my cooling system, I found that the sender was the incorrect
unit to interface with the gauge, which threw my reading off slightly. As I
recall, Stu Brennan has a post on the STOA or Mark Olsen's website that
gives you the correct ohm and volt readings from the sending unit to
diagnose it. This is an excellent resource to start with.
Keep in mind also the Tiger mantra: "Chances are if it ain't puk'in water,
t'ain't over-heat'in"

well the speed limit is only 55. I will get a contact pyrometer in the
morning and check it out. I have a 10" pusher fan and the same fan as
cullen. it is the 14" plastic fan by flexalite. it moves allot of air! by
that I mean I can feel allot of wind when I rev the engine while I am under
the hood. the advance may be the problem, I timed it by ear. but it starts
easy and accelerates nicely. to tight? well I did not build it myself so I
cant say. it does not seem to bind though. it accelerates the same hot or
cold. I thought the temp gauge might be off but it is a new autolight and
sender. I also lifted the 13 pound cap today. it heats up faster on the
highway then when city driving. I really do not know.
