[Roadsters] Not buying 1500 Motor temperature gauge

[Charlie Hubbard]

Just wanted everyone to know that my 64 SPL310 is now back on the road here
in the Dallas/Ft Worth area and I'm making progress with shaking down all
the nagging issues that go with such an old ride.  The temp gauge shows to
be running too  hot, but I think that I've proven that the exhaust is
cooking my after-market temperature gauge sending unit.  I used one of those
infrared laser pointed thermometers to take temperature readings on the
radiator, upper hoses and thermostat housing.  I replaced the thermostat,
timed the motor, set the carbs, changed the antifreeze with 50/50 distilled
water & Water Wetter and the radiator to a recovery system (thanks Graeme).
All temperature reading on the thermostat, radiator and hoses ranged 180-187
F.  The temperature sender was 190-230 deg., depending on if you were
pointing it to the left side of the sender or the right side (nearest the
exhaust manifold).  I think that the after-market gauge is accurate, but
it's getting cooked by the exhaust manifold.  What a stupid place to put a
temperature sensor!  
 
Has anyone  taken similar readings on your motor hot spots?  It would be
nice to know what temperature the other 64 1500 motors are running.  
 
Respectfully,
