Where does the extra 19ci. come from? Is it bore, stroke, or a combination of both? The reason I ask is because if you look up pistons and rings in some catalogs, they only list a 216 in 1948. If I'm not mistaken, an "FEA" prefix is a 235, correct? So why don't some companies list stuff for the big truck, or RPO 235 in '48? :confused:
