I can't find either one of those numbers on the lists I've got, are you sure of the numbers. For the BB you're going to need the biggest 3 core stock rad that'll fit with a good fan and shroud or a good aluminum 2 core from any of the majors.
They both measure 26" across and I do believe they may be newer than 1974.The part numbers are the 4 digits than a space than the 3 digits.They also have a pentastar on top.I went online and found only numbers up to 1974.What is the difference between a 26" smallblock radiator and a 26" bigblock radiator,I suppose the number of cores right????
Thanks!!!!!!!Will this cool a bigblock???????I found out there are 3 cores in it by feeling inside the radiator cap area.I HOPE this is not a stupid question!!
yes it should be fine. the only thing you will have to contend with is the top hose will connect on the opposite side for a small block vs. a big block...
