Hiya Jon! Sounds like a fun project that will be an interesting (at least to us anyway) car in the end.

You're talking about swapping the entire engine/fuel injection system right? I wouldn't blame you. Why ditch the Bosch Mechanical FI? After 30+ years, every day it starts is automatically a good day!

I wouldn't do it without a complete donor car on hand. I recall a great many LITTLE differences between later 240s and the '76 I've had experience with. Worst case you have to hack into the ignition wiring to add a circuit or two, or fool the speedometer circuit on the donor computer? If the donor uses a flywheel sensor, you'll need the donor bellhousing, but the original M46 will fit (I like the old style OD switch).
