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
how many cfm's are required

I would say that you need to find out what works for your combination.
Many factors come into play such as : ambient temp, timing and such.
It gets stupid hot here in California but my car has kept its cool with a Black Magic fan and a Northern aluminum radiator ( I believe they make the Summit brand)
My old 3 row stock radiator and the fan you mentioned didnt work for my setup.......hope this helps

This may cool your motor just fine in the spring, fall and winter..However, this is somewhat difficult to make a call on based on several unknown factors..If you like the shroud then go that directions..If the 14" fan does not cool your motor as needed you can alway go up to a 16" fan that will give you about 1900-2100 CFM's if it will fit your shroud...Then I'm quite sure it will cool your motor just fine...

Get the largest CFM fan you can squeeze in there. :yes:
More CFM can't do any harm on a thermostatically controlled fan, and it'll give you cooling capacity to grow into, or just cool very well anything you currently have.
1585 CFM sounds a bit light, but its efficiency/effectiveness or output all depends on what pressure the fan's CFM rating was tested at.

I will guarantee you that 1585 is not enough... learned from experience. I run a becool radiator with a spal dual 11" setup (shroud covers entire radiator). The cfm rating is 2950, on a hot summer day with the air on, it will start climbing after about 20 minutes of idling. W/O the air on, it's fine.
