need feedback on clutch vs flex fan and shroud

I don`t know how much h.p. ur trying to cool, but that single 16" wouldn`t cool my 440/505----------------------P M me ur phone # for pics.

Was not going to use their fan but rather a manual with clutch.

I think getting a shround for the ec2374 is going to be a pain in the @$$.
