rear gear change advice

[JOZW30]

I have messed around with the IR gun. I was using it to look for any crazy hot spots but everything seems pretty symmetrical heat wise. If I remember correctly the temps were lower on the lower hose by about 10-15 degrees.

I just pulled the car out of the car jacket Sunday so I still need to tune and change fluids, so no big deal to drain radiator and try to pull some of the block plugs to see what kind of mess I end up with. I keep thinking it's a flow problem.

Anyone ever done this before?

Plowman, I need to pick up a coolant gauge but I shoot for 50/50. I didn't know too much antifreeze would cause a car to run hotter. Can adjust that when I refill from trying the block plugs. I only drive the car in Ohio summer (hopefully soon AZ, so I better get his fixed!), so what is a good mix/ratio to shoot for? If I pick up a coolant gauge what temp is best?

I do like the 3.73's............

Appreciate the input.
