Notice I also said less work ... with the 01+ Escape engine, I don't have to touch the timing cover/components, which from my research shows should need to be replaced with the 2.5L unit since the sensors are in the same place and the pulsewheel is already set to the 2.5L setting. Someone correct me if I am wrong.

So, if the above is true, then all I would need to do is ensure that the engine is not worn out with a compression check of each cylinder. If all is good on the compression check, I would just need to replace the rod bearings and be good to go ... IF I keep the 3L cams. Otherwise, she will need a teardown of the timing system to retrofit the SVT cams & then be retimed.
