Hey buddy how's it going? You could bolt all the TBI stuff onto your '73 but I don't think you'd notice any power difference-driveability would improve though. You would have a lot of wiring to do as well as swap the fuel tank and lines etc. A Magnum would be a sweet swap but then you would have to swap the entire motor. I'd consider something like a Holley TBI setup for your rig-less hassle to install and probably less money when you're all done.
