I could be wrong but I believe Jensen also used Mopar engines in some of their cars. They were best known for overheating.
Also in the back of my mind is that the type of limited slip diff the SVX employs was a Ferguson design. They also developed what was known as the 'Ferguson System', a precursor to modern AWD design. Something makes me think one of the first to use at least part of that system was Jeep Wagoneer, as 'QuadraTrak'.
Another interesting, little known European make of that period (but not AWD) that used Chrysler V8 power in several models was Monteverdi. Do a search for Monteverdi
