Overheating issues on a rebuilt 360

I bought my radiator for a hundred and fifty bucks from Summit and it works great for my 410 Stroker with high compression...
Might have to give that one a try cause I was looking at the cold case radiators and they’ll run me about 360
My build is obviously a 360 with Keith black .40 over pistons with eagle rods, 292 duration on the cam with .508 lift J heads
3800 stall converter, reverse manual valve body, 4.10 gears it was built for the 1/4 mile I’m slowly trying to bring it back to a street car
