Fan shroud hardware on 68 Barracuda small block

Why do you need the shroud? A/C car? Not cooling good enough? HP engine now? By the looks of it, an aftermarket fan, and it's too far from the radiator. Some aftermarket fans are absolute junk for street driving. You need one that pulls some air. A shroud is not usually needed for a fairly stock non-A/C car.
Thanks cudamark
I have seen many cars with and without the shroud so not sure if needed but summer time it does get hot. I only have a dummy gage which does not show temp but with heat gun can get up to 215. The engine has a little bigger cam but not heavy on the HP as well as no AC. The fan is 2 inches from core and waterpump is 3 3/4 .
Do you think something like this would fit and do just as good as adding a shroud? Certainly should be easier. Thoughts?
