The crank sensor is set up with the flywheel/torque converter and should be convertable to work, someone has to have done it so not a major issue there, as noted, distributor makes the cam sensor function, and although the heads can be redrilled to work with your heads, the Magnum head swap would be a better option, new heads can be gotten cheap, exhaust manifolds would be needed, too, but yes, the stock heads could be redrilled, bolts are straight up and down, not at an angle. The other option is to use an aftermarket single plane intake and drill the injectors into it, add a throttle body to the single plane intake, which would be easy enough to do, then add all the sensors and fuel rails. The electronics package isn't that large when you take the PCM and injector/sensor harness apart from the rest of the harness, a lot less complicated than the competition from what I have noticed. Get a wiring diagram/good manual for the engine you intend to use and do some comparisons for the setup, then start identifying the modifications you will need to do to make it work. Essentially it is sensor placement, injector to manifold installation, and fuel system installation to handle the fuel pressure. Time consuming, but very doable.
