Does mixture directly affect temp gauge? 140-160 1974

The tightness of a new motor is mostly in the piston ring to cylinder wall interface, and the lifter to cam lobe as well. With a few miles that extra friction will be reduced, and more than that burnishing takes place, and the engine turns quite freely. This is all normal, and with modern "plateau" honing techniques, the initial friction is much less.
Bearing clearances don't affect the tightness and remain stable (or at least they should) for nearly the life of the engine.
