Greant Questio
It depends on the engine and what demands. I run hot big blocks. I had a Davis, dual fan and it was excellent. I just put in a bigger engine and I changed to an AutoRad. THe ONLY reason was the last percentage is more focus on presentation than I personally think Davis is. Now if I was racing or make tremendous off road demands I probably would have stated with Davis. But I went 1.5 tubing and dual viper fans and the more polished look of AutoRad. It will be plaenty for my road racing and showing usages. Both do cost but it is a critical part of the equation!
