Nothing mid-grade about that, unless she's slow! ;O)
I'm old and invisible to her and those like her
406's were only produced a couple of years; 1962 and 1963, I think. The 427's came out as '63 1/2, and that was the end of the 406. The 406 was available available as single 4 barrel or 3 X 2's. 352, 390, 406, and 427 were members of the FE (Ford, Edsel) engine family. A unique feature of this design was that the pushrods went through the intake manifold, and the valve covers actually covered part of the manifold and the heads.I thought the tri-powers were 406's?
Although the 410 Edsel engine (MEL block) was first, there was also a 410 FE engine for Mercury in 1966-67, basically a 390 bore with a 428 stroke. With a 10.5 compression, it was rated at 330 hp. and 475 torque.406's were only produced a couple of years; 1962 and 1963, I think. The 427's came out as '63 1/2, and that was the end of the 406.

The 383, 410, 430, and 462 were in the MEL (Mercury, Edsel, Lincoln) engine family of a different, concurrent design. The 430 was usually a Lincoln motor, but was optional on some SquareBirds.
We still have those pumps here in my neck of the woods. They serve up two grades - Regular & Non-Ethanol.
