Sorry for re-asking this, but as I begin fiddling with mechanical and electrical components for my project 6 conversion, I am still pondering this decision.

The car, when finished, will be shipped to Europe where my wife and I can use it when we're there, and do some rallies, trips and such. There will likely be (months-long) periods of no use.

Have most of the necessary stuff for the build, (included with the '71E motor-entire MFI, fuel filter/console, complete electrical board, fuel pump, etc) all from 'donor' car...

But I'm beginning to sense that the complexity of MFI (transducers, fuel system, micro-switches, etc.) could prove challenging. A good set of PMO's on the other hand: basic fuel pump and regulator, MSD 6AL, and a spray can of ether may be better suited, again given the intended use.

So, I welcome thoughts and opinions-thanks

There is a lot to be said for the simplicity of carbs. I actually fixed the float on the six with some "percussive maintenance" using a rubber mallet.

In Europe, like it is here in the states, carbs are obsolete. So the availability of parts is limited. However the only specialty part on any aftermarket EFI system would be the ECU. Aftermarket EFI uses sensors and actuators from current production cars. So I would argue that the availability of parts for EFI is better than carbs. And with a notebook computer or even a phone you can access the system and it will, for the most part, tell you what failed.

So I think your argument about parts being "hard to obtain in a pinch" is not true. I can walk into a FLAPS, and get a replacement for a failed injector, a TPS or a MAP sensor, because they are all sourced from production cars. All that is needed is a record of the part numbers for the sensors and actuators installed on the car.

Another advantage to EFI is that professional help with anything on the system is only a Webex meeting away. In today's connected world, the guy that built your EFI system can remote into your computer/phone and help to fix any issues with the EFI. Having an expert available to help, even remotely, is invaluable.

I don’t know what languages the OP speaks or where he will travel. Having lived in a small town in Southern Italy for a couple years and not being fluent in Italian, I can only say that it won’t be quite that simple.

Ah, but that is the beauty of an interconnected world. You don't need someone local to you to help with the troubleshooting. You can get on a Webex/Zoom meeting with the guy in the US that installed and tuned the EFI system. He can remote in and help you with the troubleshooting. Then using Google translate, you can type in your parts needs in English, and be able to show them the Italian translation to get the correct parts.

From experience in Paris, communications is always an issue. But the internet is becoming the universal translator that Star Trek showed us.
