4.2

OK so I have spent the last hour online trying to figure this out with no solid info on the 4.2L V8. There is a 1980 Mercury Capri RS for sale, with said 4.2L V8, that I am very interested in picking up. As most of us know 1980 into mid 1982 the Ford fox platform had the 4.2L V8 ... not the 5.0...
