I got a 1966 Chevelle, run a 454 with long water pump. I have 2-3/4" appox. clearance from fan to radiator.
other stats, Alum radiator, shroud, 160 thermostat.
I currently run a Flex Fan and a 14" electric (on front) fan. During the Nuclear Summers here in Deep south I can keep it at 200 deg. in traffic.
I am happy with that. I can keep it at 180-190 driving.
But it sounds like a damn Bus taking off, I know it's the flex fan raising hell, So with out spending hundreds of dollars, I thought a OEM stock 5 or 7 not sure on blades might be quitter and keep it cool also.
I don't have enough room for a clutch fan or good high CFM electric fans.
My question is 5 or 7 blade which is best?
and will they cool better or just as good as the Flex?
