I have a 2001 GT that has developed a low end knock. I have sitting in my garage a low mileage 5.4 from a 2002 F150 that was intended to go into another truck I had. If I replace the 4.6 with the 5.4 will I have to get it tuned? Please keep in mind that this is by no means a race car. It's an all stock auto convertible with cat back and a CAI. The reason I'm looking at the 5.4 option is I have the motor and I'm having a hard time finding a reasonably priced 4.6 with low mileage. From what I gather it will run on the stock 4.6 tune just not optimal. Also it appears I should get a really nice increase in low - mid-range torque which would be nice.
Thanks
