I had a cooling problem at the Track last weekend..it over-heated after a pass. I installed both Fans in the Factory positions, set them up to where both come on with a Manual Fan Switch. Both Fans are powered by a circuit I setup using the Factory Relays, so it's not straining the car any.

I took it out earlier tonight and ran the dog **** out of it..I ran it up to 120mph(got there pretty quick..) and came down to a stop, turned around and did the same a few times in a row on a back road, it didn't get above 220 the whole time. I have the Temp Sensor positioned in-line on the Heater Core Line coming out of the Water Pump..basically the hot side of the Engine.

It's money now..

Nice. Maybe those there GM engineering folk knew where to put them thar fans.

Yeah about the temps when the fans come on stock...... I have a manual fan switch, and my A/C wasn't working, it was way low, but the guy tried to tell me that running the fans before they are supposed to come on sets a code. I never heard of it, as I had run it that way for 2 years before any issues.

Hopefully that the last bug in your system there, when will it be all out time?

I dont know how many miles you have on it but I will bet my bottom dollar, you need a radiator. I had delt with that issue and replaces every part except the 102k original radiator. Once I did, I never had a issue of overheating, it radiator had pin hole leaks that I only found out after having the radiator hot tanked at a shop.

I am looking into it..if I do change Radiators, I am getting an LS1 one..that way everything matches.

Might possibly have 1/4 mile results Thursday..

are you talking putting a stock ls1 radiator in there? i've always heard that the lt1 radiator is better because it has a thicker core something like 1-3/8th inch core on the lt1 rad and like 1 inch on the ls1 radiator
