71 Nova Cooling Issue

[acsmall3]

Not a huge deal just concerns me a little.

Setup:
290hp GM crate motor, Summit Direct Fit Alum radiator, 14" Flexa Lite fan, aluminum catch can, 180 degree stat, stock water pump.

Issue:
Car gets hot (210) in stop and go traffic. I haven't seen it go above that but I would think if my system is efficient, it would keep the temp within 5-10 degrees of the thermostat temp.
I have no fan shroud but plan on getting a Mahhafey Motorsports custom shoroud (can't find one to work with this radiator)

Do you experts think the fan shroud would help with this issue? I am worried about the Vintage Air A/C when I install it and the 383 motor when it goes in.

Thx for any help/advice.
