EFI would make for a much nicer daily driver. But, it will be much harder to setup. You'd need to wire in the ECU and all the sensors. You'd small auxilary surge tank. If the engine sat for while you may have a few injectors to replace ($$).

 

The alternative is to just bolt up your carbs. Thankfully, Nissan made all the L28 heads backwards compatible with the older intakes. You will need an electric fuel pump since the Head on the 80 engine won't have the hole for the mechanical one. Other than that, you're left with the standard fiddling with the carbs...
