Help Swapping Engines?
88-97 T-Bird parts should interchange. Verify this by calling your local junk yard and ask them. They have interchange databases that tell them what years are interchangeable and if any otehr models would be suitable for a complete swap. Putting a v8 in a T-Bird should be easy, since the cars came factory with them.
Don't forget you will need to change the front coil springs, and possibly the shocks. Engine mounts will bolt right in, as will the transmission crossmember. The wiring harnes will be a direct fit. You might have to change the fuel lines, depending on how they are run, and if the fittings are different. I may have missed some items, but you get the point.
