Stovebolters: I am still noodling on radiator options for a '52 3100 with an LS3. In the enclosed pictures I am showing the original radiator and its support frame on the chassis of the LS3 build. Since the body of the truck is completely disassembled, I cannot get a quick reading of how much space might be under a closed hood for a taller radiator, so I thought I would turn the problem over to the community here, in case someone has already determined the limits under the hood. Notice in one of the pictures, that the radiator cap is just barely taller than the highest horizontal part of the radiator mounting frame. How much taller can I go above that horizontal bar with a taller radiator and cap? For example, I hoping that the entire top tank of a new radiator could be positioned above that horizontal top bar of the frame, and still have the hood close gracefully. That might imply say 4 inches of top radiator tank above that horizontal bar. I welcome the common sense advice of my fellow Stovebolters around this question. Thanks.
