Never have heard of one, but that certainly doesn't mean that one didn't sneak out the back door at Ford once upon a time.... Next time you're among the old Ford parts guys, I sure would like to find one of the old 4V Autolite inline 4V carb and intake setups sometime....and not have to rob more then a couple banks to own it..

FFR should be around sometime, hopefully he can shed some light on what your block might be.
