What is the "best" temperature for an engine to operate at? In my case, a 292 that seems to be a little tired, and is never pushed for hard acceleration. But it does do a lot of interstate miles, usually 65-70 MPH.



What is the "correct" way to measure the temperature. I have the dash gauge, but should I trust that? Am I better off also measuring another way?



Are some thermostats better than others? What temperature rating should I get for the thermostat?



I don't think I've seen a fan shroud for a 57, or any other Y-block. Are these available? Will it make a difference? What about using an electric fan? Pusher or puller? With or instead of the engine fan?



Summer is coming and I want to be ready! Thanks for all your help.
