oil temp

Just like a coolant temp sender is fitted at the hottest part of the engine prior to the coolant going to the radiator, the oil temp sender is best located as like Patricks or my case as above.

As noted here ( https://www.460ford.com/threads/gpm-...38/post-833782 ) the standard volume Ford 460 oil pump is rated at 19 GPM - that's 76 quarts PER MINUTE - presumably at highest RPM. At that rate an 8 quart pan will have it's oil replaced 9+ times per minute, but obviously fewer times at lower RPM. I suspect FE and Windsor engines aren't that much different.

Whether bypassed to the pan or pumped into the engine, the rate of flow in the oil pan will ensure any cooling in the pan is minimal. We don't need to worry about whether the oil temperature is off by fractions of a degree, which is the likely effect of such cooling at those flow rates.

My temperature sender is in the lower front wall of the pan - I'm not in the least bit concerned about how accurate it is.
