It occurred to me that in order to upgrade I need to know the original spec. I'm also keeping in mind that I will eventually be installing a built 2L. Does anyone know the cfm output of the original fan? Also does the stock temp sensor/ fan switch keep these engines operating in an ideal range or is there room for improvement there with a different temp switch?
