I think a lot of the stuff you read is speculation or opinion.

Perhaps Legate was referring to the
aluminum 390 that Ken Miles ran in CSX2196 at Nassau in 1964. It would certainly have been lighter than the iron block FEs. But I don't know if that's what the weight distribution calculations were based on - just speculating here.
