    I want no know if I have a s550 car crash I can get the coyote long block out and just put in the s197 and works with the s197 ecu or I have to change everything?

    The other thing if I can use the s550 short block and use the s197 heads? What else I need to do?

    Sorry for my rusty english and thanks for the reply.

    No, you will have to use the control pack to run the engine.
    No, the short block will not work with 3v heads.

    by s197 heads do you mean coyote or 4.6 heads?
    coyote should bolt right on, but it is not the same architecture as the 2/3/4v mod motor

    2G Coyote block with 1G heads is okay. But if you took the time to do real research instead of just expecting someone here to answer your questions you would already know this. You would also find out the 2G heads will both work and they flow better.

    EDIT: Swap the entire front timing cover and all associated bits (A/C, tensioners, etc....) so it matches the '14 and swap the intake and everything from the cylinder head and up and also the exhaust. Basically use all the long block from the 2G with all the other parts from the 1G and you should be fine.

    It is my understanding the G2 Coyote engines have a different firing order. I am not sure about the truck motors and if they are also G2s. Gen 1 Mustang engines and G1 Truck engines are said to be plug and play if you swap front covers and oil filter housing. My issue, I am asking if some left over Boss 302 long blocks were installed in early build 2014's. Without a doubt, the early 2014's have Boss 302 ECUs.
