Motor question
If your van came with a 351, then a 351 will go back in it.
Unless you are buying a crate engine specifically made for your van application, you may have to transplant van-specific components to your long block to make it work in your van.
Whenever I have replaced engines in a vehicle, it is typical to have to transfer lots of bracketry and other components from the old motor to the new motor. I've never done this on a van but it's the same game.
The real trick, I suspect, is if your hot-rod motor has some custom intake setup then you will have to make sure that fits in your application. If it's not a factory intake manifold then you have to figure out how your throttle body and air intake is going to mount to it. Also, will the factory ECM work with your new hot-rod engine? If not, then what?
Someone above mentioned upgrading the fuel delivery system. To me that's the least of the worries. If the stock high-pressure pump doesn't deliver enough pressure or flow that can be pretty easily replaced.
The real trick to me is fitting the intake system and the engine management electronics which will expect all the relevant sensors to be in place to manage the engine.

So a little more about me I was paralyzed at age 23 and this is my 2ed 93 and movined my handicapped stuff over to the 2ed van short story. My 1st van I got t bone so I moved all my add on parts on to this van so I can still drive. Always thought making a econoline with a lighting parts would be cool. But was told would not work so I decided just got a new motor. If I'm doing that a little more power would be nice.I just look at it I know what's been done to this ride.even that it got problem here and there. I do 1/2 marathons and do row competitions. Know the head gaskets are going out. The shop said it cost the same to redo head gaskets or to put new motor in. If I go with new motor I have the cost of it. But I'm ok with that because I know then the moter is new and not have to worry about that down the road. One day I found this site and was just seeing what i could do to the ride. Do appreciate everybody's input. So that's a little more longer story of this van and me.
So, if you are dealing with a standard garage, they are probably going to steer you away from any kind of "street rod" upgrades. What they know how to do is replace the stock motor with another stock motor where they just swap over the intake and brackets and sensors and away you go.
Doing a "performance upgrade" is beyond the calling of most standard garages. They probably have the skills to do it, but that is not what they are set up to do. They want to do standard repairs at standard labor rates and get you in and out. So when they tell you "you can't put that 351W engine in your van" what they are really saying is that they don't want to put that 351W in your van.
If you really want to do a performance upgrade on your van you will need to find a shop that does that kind of work. Because, it won't be as simple as just swapping out the old long block for the new one. Someone will have to figure out how what kind of intake system it needs (maybe it will work with stock, who knows? Maybe there is an Edelbrock intake that gives better performance while retaining all stock mounting points? ). If you swap out the intake manifold, will the injectors be in the same place to use the stock fuel rail? If you need a new fuel rail, maybe the fuel lines need to be modified to hook up to the new rail.
It might be possible to use an upgraded long block with some better lifters, better cam, performance heads, and keep everything else stock. But you probably won't get full potential out of it without headers and a good intake to go with it.
All of these things are things that a "speed shop" knows how to tackle.
