Engines factory rated in excess of 300 horsepower (the 300 horse 327 doesn't count because it is a 275 horse that got an inflated horsepower rating to compete with the 392 cube hemi under the hood of the Chrysler 300) had a three eighth inch (ID) fuel line. All other engines got a five sixteenth i.d. fuel line. Since all BBC engines exceeded 300 horse they all had a three eighth inch fuel line.
