John, I build SBC's and I had the same thoughts when I first got my 92. So much so that I put in a manual switch to turn on one fan and used it.

...If it bothers you, you can put in a switch for $4 and run the fans. In traffic, it will take a few minutes for the temps to start dropping.

Based upon the work of PCOLT94 (an electrical engineer) on corvetteforum, I installed a manual fan switch on my '96. It worked fine but threw a DTC and illuminated the Check Engine light. I was more uncomfortable with the illuminated light than the engine temp and removed the switch.

Spal fans won't help this at all at this point. A larger radiator MAY drop temps but only to 195 (that's what your thermostat opens at). Going to a lower temp than that may do nothing but build up crud in your engine.

I don't understand why you would say increased air flow through the radiator [at low speeds or idling in traffic] would have no effect on engine temp. Isn't increased airflow the very reason the fans cycle off above 40 MPH?

Relative to "building up crud in the engine," do you mean within the cooling system or the fuel intake system? If I run an 80 - 100% water mixture with the No-Rosion products, there's very little to cause crud in the cooling system. Intake system crud should be handled with proper A/F mixtures, No?

I'M STARTING TO SENSE A PATTERN HERE. I don't think you guys are sold on the idea of my upgrading my cooling system and... certainly not upgrading my fans. And, in some sense I can see your respective points. With only 56K miles on my car and everything working flawlessly, I think you guys see ME as the problem, not my engine temps. You're probably right! But... please understand when driving around town, my eyeballs are glued to my digital temp gauge!!
