Paul, can you tell us offhand what those sources are? I don't doubt what
they said, but I do question the accuracy of the information given. The
"E" suffix has been used on ENGINE numbers dating back at least to the
wet-liner Standard Vanguard engine of the late 1940s and the "SC" engine
family beginning around 1953.
More often than not, "E" has appeared alone as a suffix letter to
designate _E_ngine unit. At times "HE" has been used to designate a high
compression engine and "LE" for a low compression unit. Circa 1972, there
WERE "UE" suffixes on engines in "Federal" cars to designate engines
specific to this market (such as the weak-but-still-willing 48 hp. 1296
cc Spitfire engine). Later on "UCE" was used on California-bound car
engines.
Meanwhile, "U" in a commission number seems to have originated, at least
on the Spitfire, around 1968, originally as a Prefix letter (FDU). Around
the 1973 model year -- introduction of the 1500 here -- U became THE
suffix letter in "Federal" commission numbers.
More than y'all wanted to know, right? :-)
