I just put a 496 blueprint motor in my 69 Camaro and a Holly double pumper. I'm running vintage air with a custom made 6 core aluminum radiator. I have dual electric fans with an aluminum shroud and a high flow valve in the motor. I'm still running at 220 degrees on 70-80 degree days. Is there anything out there I can use to bring the temp down?

 

what is your timing at full advance?
