The flex fans are noisier then the stock fan. 1400 is not enough. I understand they are not as effective as a pusher then as a puller. I run a 2800 CFM Flex-a-lite on my 70 with 350. Seems to work good but is noisy when it comes on.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
