Well I'll be. Wonder what the difference could be with mine being a 71 340 car and yours too. But yours has the 26 and mine the 22? I'd sure like to find out why. This has me puzzled. But I do believe with a good 22 inch radiator properly set up with a Milodon high flow water pump, 160 Milodon performance thermostat, good mechanical fan that draws well along with an electric fan to use for sitting in traffic that it should cool pretty good.
