I finally took the Camaro on the interstate a few days ago, and while it ran well - its a good thing I only had on exit to go. By the time I got off I was approaching redline on the temp gauge. 65mph/3000k RPM the whole way. Specs are: --Stock 454 --Carquest 433162 aluminum radiator --New hoses --New 180 deg t-stat --F-Body dual fans on a temp controller (but I overrode it by using the A/C wire to run both full blast) --Stock overflow bottle --Original water pump I'm running the 454 in front of a built TH350, 3.73s, 275/60r15 rear tires. Any ideas? By the time I got to work a mile later the temps were starting to come back down. If I had one more exit to go though, it probably would have overheated. Should I suspect the water pump?
