Is 4.0L OHV an interference engine?

I'm finding conflicting information on this question. It appears the SOHC 4.0L IS an interference engine, and I've seen it said that all the pushrod V6's are non-interference.
My 91' Aerostar crank has lost touch with my Aerostar cam, and before I "just" change the timing chain and gears, I'd like to know if I'm looking at an engine swap instead.

No it is not, not to say there isn't damage, if there is enough carbon buildup, that could cause bent valves.
