I don't have under drive pullies, and I still have my A/C and the belt routing is correct.
Waiting on a tune from my tuner. Should have a new one maybe Monday or Tuesday hopefully. I am getting a lot of spark knock though. He is supposed to modify the timing table to something more suitable.

99% of the time when problem arise like this and things we ok before it is something that was done wrong when put back together. it was running cool or at the right temps before it was taken apart. So there would be no reason for the rad to go bad. If you keep getting air out of the system this is your problem. You should not be creating air. You may get a little out when you first start after what you did but after that you should not create any. You have a closed system so after one hot cold and running secition all the air that was in from the repairs should have worked themselves out thru the cap and into the recovery tank. Find the source of the air and you will solve the problem

Yes. I added some gasket sealer around the cooling passages on the intake gaskets on both side of the gasket. Previously that was leaking, not anymore.

It usually is in the 185* area and gets into the 190's when I am hard on the peddle. Stays in the upper 170's when highway cruising.
So yes, I think a 180* stat would help.

Do you have the stock air dam in place under the car? It sounds to me like the fans go off and the air does not get forced through the radiator like a missing air dam.

This is not the problem. A WB set to read gasoline will read 14.7 AFR even when the actual AFR is 14.1. The WB does not know that the E10 fuel at stoch is 14.1 so it is reporting 14.7 even though it is 14.1.

That's only true if your wideband has a custom display setting. At least that's how it is with my Innovate wideband. I had to create a table so I could correlate E10 readings to regular gas. I would compare BLMs to AFR and I'll bet he's running lean. Not lean enough to cause overheating, but still lean.
