How hot do the LT1s usually run?
Yesterday i was driving my truck with the new LT1 in it and it has a stock thermostat in it. well after about 30 minutes of driving on the highway it would rise up to about 220-225 with the windows down and the a/c off. But as soon as i got off the highway onto a 2 lane country road it stuck at 180 and stayed there. Why would it get hotter on the highway?

I don't know if S-10s were bottome feeders like the f and y-cars. But it sounds like your engine is running cooler off the interstate becuase your fans are kicking on (stock programming fans will not kick on above 40mph). On the interstate there is a lack of air moving across the radiator to cool it down. On F-Bodys for example there is a plastic air dam under the car that direct air up to the radiator. You might need to devise a way to direct more air up to the radiator.

Same here. Mine will get up to 225 sitting in traffic and around town but will go no higher than 185 going down the highway... and my fans are wired always on and a 160* stat. I thought that traveling down the interstate there would be more air traveling across the raditor?

Your fans are always on and you still get to 225?!
