Basically the MEL died because the Edsel died, even though it was used in common 430/462
cu.in. in Lincolns. Ford was already working on the 385 family 429/460 for 1968, and for those
who wondered why there was two transmission bolt patterns on the 385 blocks was Ford kept
the 430/462 C6 bolt pattern on the 429/460, could mate either transmission. The MEL was also
a wedge chamber, combustion chamber in bore, with cylinder head deck flat, it really wasn't
a good flow design.

But the FE was produced in so many hp ratings and the possibilities were endless for the times
because Ford's high performance division was given a green light to compete in just about any
type of racing. In 1961 the 390 was offered with a tri-power and rated at 401 hp then came the
406 in 1962 rated at 405 hp to replace the 390 hi-perf, only to be outdone in 1963 with the 427.
Which even today the 427 SO is still a engine to contend with, one of the very first designed to
withstand a continuous 7000 rpm in a big block. To be followed by the SOHC 427 at 600 hp which
was a low rating at that time. Ford like Chrysler was pouring buckets of money in factory sponsored
racing. It's what made Mickey Thompson, Holmes & Moody & Shelby household names.
