Is there a difference in 32 4cyl upper and lower radiator tank widths compared to a flathead V8 radiator, such as more rows on a V8 so possibly it's deeper from the grille to the engine ? Or were all the tanks the same size, with just extra holes for the V8? How many cooling rows were on a stock 4cyl vs. the stock V8? I need to build a chopped down radiator for my 32 and was considering starting with some 4cyl tanks and adding the 2 extra flatty holes and having a 4 row core custom made for it? All help appreciated! Thanks!
