10:1 compression. Yes, that is an interference engine; all "Euro's" with high compression are.

N!

general rule is all the 4.5L are non-interference & all the 4.7 Euro, 5.0-5.4L 32V are interference....I am not sure about the 4.7L USA engine though?

It's non interference if the pistons are clean. If there is carbon build up on the top of the pistons, it will be an interference engine.

Simple answer... Maybe.
I know of one (idiot) owner who broke or jumped the timing belt on his K-Jet Euro S (80 or 81 IIRC) several times and never damaged the vavles. Assume it is interference, whether or not it really is interference.
