351w vs 360/390

For me it seemed like the better way to go. I only needed a cast crank and hyper eutectic pistons so the prices were much better than the 408 kits. Now when you add forged pistons the prices get closer and if you add a forged crank it's really not that different, but for an inexpensive stroker the 393 seems like the hot ticket. Just watch your compression ratio. Summit Racing has a calculator. I went with around 9.5:1, but I'm trying to build kind of a hot motor. For more of a street motor you might want to go around 9:1 - 9.25:1

And it would be no way even close to emissions legal.
An FE powered truck would be cool, but with all the Windsor parts available and it being a direct bolt-in... Kind of a no brainer IMO.
I'd imagine gas mileage to be similar, probably a little lower, but not as bad as a 460.

I'd build a 460 before I spent all that money on a stroker build. Stroker builds are great for saving space and weight, but neither are really an issue in these trucks. The 460 will be muuuch cheaper, and has way better heads on it that can support lots of power with porting and milling for compression. Under normal driving conditions, it'll be just the same as a big cube stroked 351 as far as fuel guzzling.
If I were to do mine all over it'd be 460...I hate that I can't run a zf6, and with minor alterations the 7.3 zf6 can bolt up to a 460.
Build a 460, and buy yourself some other Xmas presents. Or use money saved to buy a zf6.

I could be wrong but I think the 360 and the 460 get about the same gas mileage. About 8 to 10, maybe 12 if you are reeeaaaalllllly careful! That's what my 360 got and it never saw the high side of 10 From what I've read on FTE a 460 does about the same. Some, a bit more, some a bit less. So if you can live with that then save your money and build a 460 as it will be cheaper in the long run.
If you want better mileage than the 360/460 the same comparison, more or less, applies to the 390 and the 351W. The 351W will get a bit better gas mileage than a 390 but they are close enough. The 351W will be cheaper to build and run. I've heard of people say they get 18 mpg with a 390. I've even heard of one claim of 21 mpg but I don't believe it. Mileage in the 14 or 15 mpg range is more realistic. Many report that or slightly better with the 351W too.
Good luck with whatever you decide to do.

NV5600 bolts right up with an adapter from places like advanced adapters, I should have said that first. The nv 56 is a great trans, but I'm growing weary of them as more time goes by, *many* rebuilt trans are pure junk...ever since they went out of business it's all been china parts flooding the market with who knows who rebuilding them. All of mine are factory built, and as those become more scarce I'll be resorting to other transmissions. Mainly zf6 in applications where they can physically fit.....
I can't attest to what exactly it takes to mate the 7.3 zf6 to a 460, because I haven't done it personally, but i know it's been done. I've, however, seen it both personally and browsing the net. No cutting of bell housings and welding new ones, it's a matter of building/grafting bracketry and getting the right flywheel/starter combo. I'll be looking into it more for myself and if the cost is right I may build a 460 just to run a zf6. In the unlikely event I find a factory nv 56 in the meantime that isn't beaten to death or seller is askin ridiculous amounts I'll be mating that to my 351 and continuing to use it. I can let you know what I come up with as for the zf6 requirements if you are interested.
