what efi parts are these and can i use them on my 360 magnum

You will need an Oxygen sensor, crank position sensor, cam position sensor and injectors. I would swap out that TB for a factory 2 bbl Mopar one as that one is way to big for 360hp. But you can always try it, just night not have great low end torque with it. you will also need fuel pump, filter/regulator and line kit. I wouldnt waste my time with frame mounted pump, just do it right and put it in the tank where it belongs.
