Pi Donor Cars

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?

I dont know much about the engines from the rest of these cars, but I do know that the further you get from just using another mustang engine, the more work your in for. Im sure you know this though, and I could easily be wrong and Ford could have made the swaps easy, all I know is I was looking for a bigger engine to put into my GT (was looking at some 5.0 coyote engines since my GT has around 140K miles) and ended up just deciding to get a cobra engine once my GT's engine blew, a simple coyote engine required much more work than I thought it would take... go figure! Either way, Good luck! let us know what you find and decide on! :)

The vehicles listed above will be pretty much plug and play. They are the same basic engine, just some very slight variations with the plenum and maybe a plug location. You can also make it as much work as you want, but if you swap the original engine parts onto the donor engine, its simple. I did a swap from a junkyard Grand Marquis into an 03GT in about 5 hours....start to engine start. The longest part was swapping the front cover of the engine, and swapping the clutch and transmission. There was not a huge difference, and it would have worked just fine if we didn't swap the front cover, but we wanted to so that it would be more like the "original".

If the swap was a different type of engine, then yes, it is a pita. 4v, 3v, Coyote....those are a lot more difficult to swap because major changes have to be made.
 
Ah I see! Im actually really glad I came here then! Are there any 4V engines that would work (at a cheaper cost) besides the engines from the Cobras and '03 and 04' Mach 1's? ever since I looked at the horrors of trying to put a coyote engine in my GT ive pretty much thought the only way to put a 4V engine in my mustang was through a Mach 1 or a Cobra!

And thanks for the information! Im relatively new to cars, and therefore Fords ways of production, so I had no idea the engines were that interchangeable!
