Personally I consider this is a no brainer but I figured I'd ask to get a consenus here in the forum.

A used car salesman with devious intent would try and trick the oil pressure gauge like this. However thicker oil takes more pressure to circulate, which means it is not getting through the passages any quicker. In fact quite the opposite. Especially when the upper end starves on cold starts! This could lead to further damage beyond that which originally caused the low oil pressure in the first place.

You can put me down as a 'no' vote.

Want more pressure? Get a high-pressure pump !

Nothing wrong with that.

Yea that should be okay, however as recommended in colder climates you could use 5w-30 for better cold start circulation. I would not hammer on your LT1 for the first couple of minutes on a cold day. Let her warm up a bit and you are good to go.

No,
Thicker oil is for larger clearences.
You will ruin your motor by running the wrong oil.
Pressure is not what protects bearings, bearings are protected by centrifical force.
Too thick of oil = oil starvation= rebuild.
