Ford did some real parts swapping back in the '60S , having been around the auto wrecking business during that time . 390 blocks were cast with 352 numbers for a fact . Don't know about the 302 /289 deal and perhaps the 302 was indeed an owner installed thing or they switched emblems, an old street race trick .

I agree with the parts swapping by Ford. Without giving my age away, as a teenager I worked in a automotive machine shop in the early 70's. I would find several different casting numbers on Ford blocks at times. I even seen GMs come in with bored blocks and valve guides replaced, on stock motors. You never know untill its open, what they may have done to get it out. I can't speak for todays products, but the late 60's and 70's sure had some left overs in the new products going out the door.
