Not an LT1 mod question, but I need help from an LT1 guy
does it just happen to be warmer outside than you are used to? The stock fan turn on temp is somewhere around 220 degress which to me is reallllllllllly high. but apparently not to GM. I dont think you have a problem at all. Im not saying you dont but if your car is bone stock it is normal to reach temps around 210. That was the first modification i did to my car, lower fans turn on temp.

Ok I can see one fan on the pass. side, with the air on and the car running it wasn't moving. It looked like there was another fan on the driver side that I couldn't see, but with the air on, I could hear something that sounded like a fan coming on and going off every few minutes or so. I do have an update though, after filling it up tonight and turning it on, w/i just a minute or two I do see a little smoke coming up from, what appears to be the bottom of the radiator on the passenger side. With it being dark, such a low car, and me by myself it was hard to narrow anything down, but it was smoking from below the radiator.

Fans wont kick on till 226*, BTW. You may have air in the system, try and give it a bleed. Replace the radiator cap as well. If it runs at 190 or so at speed, theres nothing wrong with the thermostat. Let the car heat up and see if the fan kicks on when the car hits 226* or so. If it does, it's running exactly how it should. Does the gauge move when you rev the engine when it gets as hot as your saying? If so, you have an air bubble in the head to bleed out. Air bubbles will form and make the car a REAL PITA to bleed (basically never) if the radiator cap isn't good. At this point, I doubt you have a bad waterpump.
Oh, and the steam coming from below the radiator is probabaly just water evaporating of fteh radiator as I'm sure you spilled some when you filled the radiator up.

Yes, it does. IIRC, the temp gauge goes to 260*, with midpoint being 210*. The reason it doesn't boil is because the coolant is under pressure, the greater the pressure, the higher the boiling point. The first fan or low speed will kick on at 226, the second or high speed at 235.

Well I was working on it this morning, trying to find something wrong and see where my coolant was going (not in the oil), then I noticed the wind blowing and some smoking coming around up front, and looked and it's puffing some smoke out the *** end. So it appears I've got a blown headgasket and the block is drinking my coolant and farting it out the rear end lol
I'm just going to try and sell the car as is for like $3400 and let someone who's more into LT1s and working on them replace the gaskets and have a nice car.

Are you sure that what your seeing isn't normal warm up condensation? If you have a blown headgasket they tend to POUR out steam. Like a lot. A whole lot. Doubt thats what it is.
I had a similar heating problem, turned out to be air in the system but my fans weren't coming on either. Try bleeding the system and running the ac (to get the fans going automatically) and see if that keeps your car cool.
i have an issue like this as well
my fans will turn on but only if I jump the aldl or have the ac on. i have replaced the temp sensor in the head and water pump. any ideas 94 formy

what i did was hook a manual highspeed fan turn on switch, it will turn both fans on. i designed built and wired it my self, very simple now that i look back at it. In your fuse box under the hood you willl have two or three fan relays, just do some research and figure out witch wire is the trigger wire for you fans basically what atrigger wire is is a ground or positive current that is sent to in this case a relay or two or three that activates the relay. In my car all i had to do was hook a ground wire to a toggle switch under the dash and run a wire from the other end of the switch to all of the ground trigger wires on my fan relays. viola when i supply the relays with the ground(alomost no amprages passes to turn on the relay) the fans turn on and another nice thing about it is that i need to add no fuses no large wires and the fans pull power from the stock wiring and if i leave the switch on and turn the car off the fans will turn off also!!!!!! this wont solve your problem but it will solve that stock VERY VERY HIGH fan turn on temp.
