    I have an 01 f150 with 5.4 that has 293,000 miles on it. I have been offered an 08 5.4 with 40,000 miles on it for free out of a wrecked f250. I have pretty much determined that there are a lot of changes made from those years---- 3V heads, cam phasers, etc. My question is, Are the short blocks the same? Can I recondition my 01 heads and install on the 08 short block utilizing my 01 cams, timing components, and intake setup? I know of several changes made, but if the blocks are the same, I would think I could swap heads, intakes, and timing components to create and engine with far fewer miles on it. Are there any problems I could face in doing this?

    It would be easier to just swap motors. Transmission mounts are the same.

    wouldn't the cam phasers and relevant sensors require changing ECM and wiring harness?

    IMO an ECM and harness swap would be a requirement.

    Yes ecm and pcm and wiring. Pretty much everything that runs the truck.

    You'll also need a custom time afterwards since I'm assuming you want to keep the 4r70w in your 2001. The 11th gen PCM is not set up for that transmission.

    Honestly, you'll need a lot to make the 3v work in a 10th gen. It would be a lot of headache I think. Do some more research to see if the blocks are the same and I would just keep the 2v heads..

    Good luck.
