Denny, you want to handle this one or should I?

Oh, what the heck. The 406 had a 4.13" bore and a 3.78 stroke and was made from 62 1/2 to 63 1/2. the 427 replace it as the top of the line.

An FE with 4.05" bore and a 3.98" stroke is the 410 used in the Mercs and as R Pope said, he has found a few in 70's Ford pickups.
