Yeah my Custom ordered 78 F-150 Lariat was fully option with a 460 and a C6 transmission and naturally the Ford 9 Inch rear.Imagine all those big block engines back in the day with fuel injection, half of us kids would have killed ourselves. Those clutsy carburetors prolly kept us alive.
It had quite a few mods and was a very healthy running vehicle. I also installed a gear vendors overdrive, which made it a very high speed vehicle. It was way too fast for those bias ply tires! It had the absolute widest tires for back then. It was those N50-15 Mickey Thompson eye-bone tires! We thought those were huge back then and they were for back then. You definitely can't say that today!
I would definitely fuel inject it! I'd probably throw them some parts from Kaase
