Hey guys, my 98 gt is getting up there in the miles and recently has either a bad hydraulic tensioner or a rod knock from what it sounds like. I already have pi heads off my buddy's dad's lightning but now I feel like just doing a full PI engine swap. What cars do I have to work with here to get one aside from a 99-04 gt. I know f150s had them but I was looking for something I can get the manifold with. What years grand marquis and crown Vic's can I use and is there anything else out there? Or should I just save up and do a 4v from a Lincoln?
