The easiest way for this car to run in Stock would be to put the EFI back on, and run it as a 87 thru 93 Mustang, which is legal with either a stick or automatic, plus you would not need to find,paint and install the 85 body panels and interior. You may want to give this effort some serious consideration and do some research before turning a wrench.

I totally agree with Rory ^^^
Good advice.
