MPI conversions

I've got a 99 Ram that is an auto. I want to pull the motor and put it behind my five speed and use the injection if possible for my 70 Cuda. I would love to hear what your price would be to get it all harnessed up. n I am ready and have the $$ now if you were prepared to get going. I suspect I would have to get another computer from a standard though, or does the trans have it's own on the magnums? Fuel delivery etc. is no worries for me, I can handle all that!
