I've played the thermostat dance recently on my V8. The t-stat is identical
except for a small vent/check valve thingy.
The Wahlers seem to have a larger diameter opening but the travel is
shorter. I've gone thru 3 or so t-stats until I found one that seemed to
allow the engine to reach operating temp but didn't cause the car to run too
warm in warmer outside temps. These were all brand new t-statsof various
manufacture. I have one more new one that I haven't tried yet. My
Thanksgiving road trip to LA was with one similar that I originally removed.
The subsequent Wahler didn't seem to open far enough to allow reasonable
engine temp while just cruising around town with outside temps at no more
