Cooling fan questions

Hey all! New here and joined to hopefully receive answers to my questions.

So my truck: 1994 F-150 Flareside 4x4 5 Speed manual. I swapped in a roller engine 351w that I built up it has: upgraded camshaft, aluminum heads, edelbrock air gap intake, 4 barrel edelbrock avs carburetor, msd ignition box, Holley red electric fuel pump, Holley fuel regulator, 180 degree thermostat, larger factory radiator (believe its 2 row) and long tube headers. Still have factory ac in it and heat.

I need to figure out the cooling fan situation to keep this beast cooled down in the summer.

As far as I can see I have 2 choices:
Choice 1: clutch fan and shroud (Simple and effective for many many years)
Choice 2: electric fan setup ( I understand all the perks of this setup but really doesnt have enough perks to it for me to think its better)

So I really like the simplicity of the clutch fan setup. (I know and have everything to do the electric fan setup already but kinda against it). So i know from the years of service that the factories made a great design with the fan clutch setup that they used even on big blocks.

The biggest question is with the upgrades i have done to the engine will the clutch fan setup still keep up with cooling it? (i'd love to hear from those that have upgraded their engines and still ran the clutch fan, tho i would be just as happy to hear from those that havent).

Thank you for taking your time and really addressing my post and questions.
