I brought my Cougar to my Ford friend and he is installing the SVT cams..... when he locks the last bracket on the cam by the passenger side the cams got stuck and do not rotate.... actually 3 of them have this issue and only one rotates?????
Is he doing something wrong or the cams are bad????​

Ok... the Ford friend is telling me that these cams do not fit my car.... I received a package with the cams and all the timing component (detailed I'm going to kill you)... the chain and all other parts that are in the package are just the same of the stock parts on my car but the cams. The cams do not fit neither my chain or the chain that is in the package.
I know at some point Duratec (when it dropped from 2544 to 2450???) started using a different chain but... the difference is only in the chain and the cams wheels or something else change in the cams itself (i.e. thickess)???​
