I’ll skip how I got here .. going to remove the stock fan on my 53 8BA slightly built in a 40 Sedan. Going to use a pull fan. Presently have a 14” push that is rated at 1500 cfm and considering flipping that to the pull side. New Walker four row that holds about 55 gallons ( kidding ) Question ... should I just go to a 16” fan with 2500-3000 cfm and buy new or try to use my existing? I am usually one for overkill but after awhile things get silly. truck water pumps, no overhearing issues now, no shroud used now, live in NC where it is 95 in the summer. Thamks!
