Engine temperature.
Had a local guy rebuild my 1976 L82. Kept the block, crank, rods & 160 t-stat. Other parts new. Now 355ci. Flywheel dyno turns 470hp @ 6200. Engine temp is 158 just below t-stat and oil pan is 200, both with IR thermo. Running 20-50 BradPenn oil. Engine guy likes it cooler under the hood. What do you guys think? Should the coolant be closer to the oil? Or leave it alone?

I prefer running a 180* on the street. Promotes quicker moisture evaporation, and being traction limited anyway I'm not particularly worried about the nominal "loss" of HP vs. a 160*. As for keeping under-hood temps down to provide for a cool A/F charge, install a properly isolated cold air induction system and it'll be nearer to ambient than can be ingested from beneath the hood, whatever the stat. My $.02.

I personally/professionally do not get all caught up in dyno numbers. They are all well and fine.....if that is your thing....BUT I am more concerned that the engine oil is getting hot enough to get the moisture out as previously stated by 'JimLentz' and 'The SkunkWorks'.
