No. Depending on your thermostat, it should run 10-15 degrees warmer. My car runs at 170-175 with a 160 degree thermostat. With both fans on, it should be running around 190 if you have a 180 thermostat, and 170 if you have a 160.
You have a 160 thermostat right? It's a LT1 thermostat, not a small block chevy thermostat?

Yes it's the right kind. I did a test drive last night (low 60's instead of 95ish). I think the problem is that when it is hot the low fan can't keep up. Last night the low fan kicked on and it dropped it to the 200 range. I'll do a data log and compare it.
It only gets super hot going slow on asphalt. Like at a red light.

Well, I finally drained out the coolant and flushed the system. It seems to be running a lot better! My mission is fixing a ticking noise coming from my valve covers. I popped the cover
This is definitely where the noise is coming from. The rocker arms I can move side to side a little and the pushrods move side to side too. I think this could be what is making the ticking noises. Is valvetrain ticking common on an LT1? It ticks the same wether it is cold or warm.
I welded this tab back to the valve cover thinking it could be causing the noise, but it didn't change anything.

I have it with roller rockers, but I didn't have the nose with stock rockers.

Supporting MemberSure the rockers aren't hitting the valve covers?

I've totally flushed the coolant and now it runs a lot better. It doesn't climb so quickly like it did. There was a ton of brown sludge in the coolant. I flushed it 5-6 times and put in 50-50. I put the 180 thermostat back in, the car is running to cool on the highway.
Ive been checking some other things on my car to see if I can find the problems. It feels like the car has a veeerrrry slight miss. It drives fine in all conditions, but at idle if you listen closely it sounds like a slight stumble. It doesn't happen with a consistent rhythm. I pulled off the fuel rail and cleaned the injectors. I reinstalled them and took the connectors off one at a time to see if the idle went wacky. When I took cylinder #3's connector off there was no change in idle. I think ive got a multi-meter somewhere, is there an easy way to test the connector without frying the PCM? I guess the important question is how bad is it to drive like this? I'm going to recheck the wires.

Maintenance on my '94 z28 pic heavy
I rechecked the wires running back and over the intake. I must have jiggled then right , because I could feel the injector start clicking. Also the idle changed when I unplugged cylinder 3.
After that I decided I would try and change some spark plugs! I bought some NGK TR-55's. I mainly wanted to check the condition of the #3 plug compared to the others. It did look different. It was a lot darker on the ground strap.
Here is #3 compared to #5
The restt I changed looked like #5. I didn't change 2 and 8. Luckily I have the worlds skinniest arms. I did it 1-3-5-7 4 and 6 from above.
It got dark on me and I couldn't do the rest. Tomorrow I will do the others and change the wires. I went for a test drive and it sounds and drives A LOT better!
Interestingly the stock plugs AC-309 looked to be platinum tipped. On 3 of the plugs the platinum puck was missing on one or both ends. The gaps were .048 to 0.87 measured with a dial caliper.
I left the stock NGK plugs at .058 I may close then to .050
EDIT: These plugs are stock (pretty sure) at 32k miles on the car.
