Whats the difference
It seems that alot of you guys like myself are not comfortible with these cars running at or around the 225 degree range. To me this seems way to hot and what id like to know is what did GM did that is different between the92,93,94,cars and the older ones around 85. I had a 85 and never had any problems with it over heating. Heck i sat in traffic going to the Pepsi 400 in Daytona Florida for hours and it never got hot. Anyone know what the difference is.

RE: Whats the difference
I would be comfortable with mine running 225 degrees in the summer if it would stay there! lol problem with mine is my aux fan comes on at 185 and my engine fan is on continuously, so I know once mine gets over 195 degrees ( thermostat setting) it is just going to keep climbing as there is nothing at that point to cool it back down.

LT1 is a higher-strung twister than an L98. More squeeze under the heads too.

The L98 is conventionally cooled so your not going to see as high of temps. GM designed it to run as hot as it does on purpose. Your just not accustomed to it and have been told probably from day one of your engine education that this is bad. Its not on an LTxand takes some getting used to in a LTx motor. Take a look here:
A key technical difference between the original 350 and the Generation II small block is the cooling system. The engine employs reverse cooling, meaning that the coolant starts at the heads and then flows down through the block. This allows for a higher compression ratio and more spark advance since the heads are kept at a cooler temperature. A secondary benefit of reverse cooling is that cylinder temperatures are higher and more consistent.
It has already been noted (above) that the LT engine's reverse cooling system enables high compression, and the factory exhaust system and air inlet systems are not well optimized for performance . However, the intake manifolds, cylinder head castings, and other base engine components are capable of supporting much higher horsepower than factory-equipped engines produced.

My LT1 typically ran between 200 and 205 once it warmed up. I have a '92 with over 100k miles. This was before I had a coolant hose break and destroy my opti, which I am now fixing[:@]. I'm not sure why some of you have higher temps.

you can have it re-programed so the fans will come on at a lower temp, and a lower temp thermostat put in to lower the overall temp, but other that that theyjust run at that temp, thats all there is to it
