Can anyone confirm the comment about 340 26 inch Radiator lower inlet being smaller than would be on a big block 26 inch radiator? I am using a 340 rad and the lower hose is same diameter from water pump to the lower inlet.
I am working thru a 440 running too warm according to my gages which I am trying to confirm their accuracy. Mine is doing 220 highway and 230 idling.
