I am installing a summit aluminum rad in my 67 and have a turaus electric fan but I am thinking of buying the 14" electric fan and shroud from summit for the rad I have part #sum 381012. It is a 1585cfm fan and was wondering if that is enough for a mildly built 350 sbc. I know the ford fan is commonly used but I like the looks of the aluminum shroud and fan from summit. Any advice would bo great. Thanks
