Best donor for MPI

Thanks for the response,
my thoughts were to use the obd2 stuff I have and make a reliable fun driver. Then, upgrade for more power. I am familiar with the stock stuff but not sure about modifications especially when you get past headers and intake mods. I have read some on the Dakota R/T forums about modification to fuel injected magnums. I just wanted to gather the correct parts the first time around and not find out that I should have gotten a different harness that works better than what I have already.
