47-55.1 GMC LS Swap Radiator question

[Hcb3200]

I currently run a stock 6.0 in my 1956 with the stock or close to stock brass radiator. Unless I am stuck in bumper to bumper traffic and its over 90 i rarely turn on the fan. (electric when I want to run them) That LS runs at 200 if I am lucky half the time its at (188) and never over 210 which is really cooler than GM runs them in Tahoe's and Suburbans. Unless you are in the need for a radiator see how it goes with what you got first.
