    The displacement is correct, but I believe that just swapping the head is not going to solve the rest of the problems that it will cause. You need to swap everything.

    I mean: Fuel lines, fuel pump, engine harness and ecu. A lot involved.

    Here is a swap from a member on preludepower.com
