Although the casting #'s say it's from a Fairlane or Torino, it could also be from a truck too. The casting numbers only indicate what that part was designed for, not what it actually was installed in at the factory. Yours being a 78, would not have had a 351W though, I believe the choices then were the 300, 302, 351M , 400, and 460. As for parts, anything made for a 351W isn't going to be year specific and should be interchangeable. The only major change to them was the 94-97 roller block, but even that only affects cam choice.

Check the pictures in his gallery, he does indeed have a 351w in his truck.
I think the only (major) changes on the 351w to watch out for, is the change from 16 to 12 intake bolts around 1971?

Figure out exactly what year motor it is ( date codes) and determine if it's ever been rebuilt. If it hasn't just knowing the year model it is, you'll be able to look up the comp ratio. Most 351's are anywhere from 8 to 1, to 9 to 1. I think only the 69 4 bbl motor had more.

That's the casting #. It only tells you when the block was designed and what it was designed for. Not actually when, and what it was installed in. The date code is next to the casting # ( for the block that is) it's a number/letter/number combination. Looks like a cast-in tag on the block. The head casting numbers are under the intake runners, date codes for them are inside the valve cover rail. Same number/letter/number combo

Yea, 1H10 would be August 10 1971. But the Windsors all had the 1-3-7-2-6-5-4-8 firing order. Sure it's a Windsor and not a 302? How many intake bolts are holding it to the heads? Should be 16 for a Windsor of that year. 12 for a 302 or a 77-up 351W. If it's a 71 351 then the comp ratio should be 9 to 1, give or take a few tenths.
