Typical cost of Radiator re-coring

Mine was just under $400, mine is a stock 66 rad, had the lower outlet moved for the newer pump, I had mine done in a high flow efficiency 2-core. My car dyno'd 300 RWHP and NEVER gets warm, wether its crusing the HWY ay 70 mph with 4.10 gears or in town rush hour traffic in 95 degree temps.
