With the 396 & 427s having the same mass & likely spring rates due to that mass, I would expect that F41 could have been kosher with any BBC-powered B-body. I do recall that on Chevrolets they specifically said that F41 was offered with Turbo-Jet V8s only.
It is what it is, and the published docs state one thing. It is great that others have chimed in with documented LS1 / F41 cars. With so few F41 cars produced and the reverting of most '69s back into the elements, we may never know the whole truth. The mystery continues.

I don't judge a man by how far he's fallen, but by how far back he bounces - Patton
a) The documentation we have for building the 1969s says they absolutely, positively MUST have the 390hp motor for F41
b) A documented car exists without the 390hp motor and with F41
Did it require a phonecall? Or if you checked F41 they didn't somehow filter it out as a technical restriction?
A year or two ago I wrote an XML grammar for defining options (Can't have A with B unless C, etc). It's not easy or trivial, so I can sure see mistakes being made or exploits exploited!
