Gotta agree with Garth. Further, on a 550-mile trip to 'Vegas one year, I ran 
a 192 degree Cleveland thermostat and got a stable engine temp of about 190F. 
A few days after arriving, I changed the thermostat to a 160 thermostat for a 
289 Mustang, and drove home. The stable temp was.... 190F. Running a Weiand 
8209 water pump with no warm-up bypass, you can do this. The 6 hr trip each way 
ensured the temp was stable and I have a calibrated gauge. So the range of 
the thermostat, at least for this test, made no difference. The next step would 
have been to use a hi-flow thermostat along with a regular one (of the same 
range) and again compare on a very long drive. But thats yet to be done. FWIW, 
there are some indications that NO thermostat will radically drop a Pantera's 
engine temps on long high speed runs, so I'd suggest pulling the thing 
completely out and driving to 'Vegas- as long as your waterpump has no bypass built 
in. See you tomorrow, Art- J Deryke
