A 5.7L Ford V8 and a 4.6L Ford V8.
I needed the 5.7L for a 2005 red ford truck (FX4) that I inherited from a relative, and the 4.6L is for a 1999 black ford truck single cab, short box, stepside (STX) that was fouling up the 4th, and 5th plugs with oil every three, or so months before I parked it. I suppose I could've rebuilt the heads in the old 4.6, but then it would still have the same old bottom end just waiting to fail. The red Ford needed an engine, it had bad compression when I took it to a place called grey eagle engine repair.
