I had a 390 in one too. All these trucks loved fuel. Not the 302s all that much I guess, but those straight sixes ate as much fuel as the 302s. The 390s and 490s, fuggetaboudit. When I bought my first 490 my cousin told me the same thing he told me when I bought my '69 Coupe Deville Ragtop with the 500 from him. I asked him what kind of gas mileage, he said " Don't worry about the gas mileage." I also bought a 71 hardtop Coupe with a 500 from him. And a 1967 Sedan Deville with a 427. I loved those Cadillacs and miss them all very much.TFIC IV = thick film integrated circuit series 4. The 70s version of an integrated circuit. Prone to moisture problems
FICM = fuel injection command module. The high voltage box that controlled the injectors. 6 liters had the worst.
I used to work for International dealers in the 90s. The 7.3s were remarkable engines. And yes the 490 gasser was a beast. Believe it or not, Ford used a lot of gas engines back in the 70s & 80s. The 330, 360 and 390 industrial were very strong but had an appetite for fuel. Then they introduced the 370 Lima another good engine if you could keep the intake sealed.
Sorry, got sidetracked, but the discussion triggered cool bits of trivia in my ol noggin.
