My first question would be, what kind of TEMP guage do you have? Are you sure it's accurate? Also, how old is the radiator? I have an 84 Z28, 305 HO. The firstthing I did was put mechanical TEMP and OIL guages in. The radiaitor looked ratty so I put a new one in. the four row heavy duty type, all metal, no plastic tanks. My car runs at 190 ont eh highway, and will jump to 230 in under a minute of stop and go traffic. The fan kicks on at 230, or, if you put the A/C switch to any air conditioning setting, the fan will come on. If I get stuck in traffic, I just do the A/C switch trick to pull some heat off. I think these motors are meant to run at 200 to 225.
