The HO CFI 5.0's seem to be rare.  I think they were an option only on
the Thunderbird.  Until I found the engine I really wanted, I was
checking the junkyards for HO CFI's.  I think I found two such cars -
one missing the whole engine, the other missing the injectors.

The CFI's are found on RWD V8 passanger cars.  I think CFI was standard
equipment in 1984-85 except on cop cars.  It was optional in earlier
years, but that was with earlier electronics.

The Ford EEC-IV isn't as hackable as GM.  But it has been hacked, and
there is a commercial product for tuning certain EECs.  Check the EEC
mailing list.  I don't know the subscribe address, but here's a hint:

To change the code in an EEC requires some circuit construction -
perhaps 20 TTL type chips or one CPLD.  Plenty of personal achievement there.

What country is ".cl"?

I guess that advice on what fuel tanks, fuel senders, fuel pumps,
brackets, and etc. to use won't be useful.
