Big block cooling

[90droptop]

Dumb newb question
But how many CFM's are required to keep a big block cool? I'm fixing to do a complete flush and replace thermostat, wanting to Ditch the mech fan and go electric.

I would not suggest that for towing. forget the name of the company but for around 550 you can get a bolt in kit from summit or jegs but right in there specs it says not for towing use. also, run a 180 thermostat, it will keep it out of the heat range where it starts pulling timing thus reducing power.
