Sorry Brad, the Ford 400 is not a Windsor engine. It's a 335 series related to the 351 Cleveland design.  

Sadly however you cannot just bolt 351 4V heads on a 400 block. I looked into it. 

Now MY 400 was a 1970. There was no such thing as smog control in 1970. That car flew.
 
If my stupid ex, after she was done destroying it, had sold it back to me instead of her friend just to spite me I would have turned it into a "strictly stock" car which is a class we have here for amateur racers. I bet it woulda done pretty good.

400
The big-block FE engine family was getting outdated, and the 385 family could not meet the efficiency requirements of the time. At the same time, the small-block Windsor engines were too small and high-revving for Ford's fullsize car and truck applications. So the company went to work on a new small-block to meet the desired levels of economy while still providing the kind of big-block torque that was needed to move 2+ ton vehicles.

The Ford 400 engine was based on the 351 Cleveland but was produced with a taller deck height of 10.297 inches compared to the 351C's 9.206 inches. This allowed for a longer stroke while retaining the 351C's rod-stroke ratio. These blocks also share the same oiling route in the block. The 400 also featured larger (Windsor sized 3.00 inch with Cleveland cap register) main-bearing journals and had "square" proportions, with a 4.0 in (102 mm) bore and stroke; it therefore displaced 402 cu in (6.6 L), making it the largest small-block V8 made at that time. It was introduced in model year 1971 with a full half-inch (12.7 mm) longer stroke than the 351 Cleveland, making it the longest-stroke Ford pushrod V8 engine. A long-stroke engine has good low-end torque. This was a good compromise given Ford's requirement for an engine to power heavier mid-size and full-size cars and light trucks. The M-block, as it later became known, was the last pushrod V8 block designed by Ford. The M-block also shares some elements with the Windsor engine family: bore spacing, cylinder head bolt-patterns and crankshaft journal dimensions.[3]

The 400 was seen as a smaller and lighter replacement for the big Ford 385 engines, the 429 and 460, in Ford's big cars. Weighing just 80% of a similar big block, it was originally available in Ford's Custom, Galaxie and LTD lines, and in Mercury Monterey, Marquis, and Brougham. Later, it would power the Ford Thunderbird, the Lincoln Continental, Mark V, mid-size Fords and Mercurys, and Ford light-duty trucks.

The vast majority of 400 blocks use the same bellhousing bolt pattern as the 385 family big-block to make it compatible with the higher torque-capacity C6 transmission used on the large cars and trucks. There were a small number of 400 block castings that use dual bellhousing patterns for mounting an FMX transmission. These castings are rare. The 400 was modified in 1975 to use unleaded gasoline.

Actually, you can.  Straight swap (onto the block, anyway).  Later 2V heads had revised water passages so may take some mods to the water jackate passages to make them perfectly match but it's otherwise a bolt on.  Problem comes in when you try to find matching intakes, accessories, etc.

A stroked 400 makes can make some darned impressive power numbers in a smaller (but fairly expensive due to lack of aftermarket support) package.

*ETA* After some checking it's not as expensive as it once was to build a performance 400 stroker thanks to Tim Meyer at tmeyerinc.com.  They specialize in 400 stroker kits.  Now, for what is a relatively modest sum in stroker terms, you can build what is, in essence, a 434 cu inch high-deck 351C that will easily hit 500/500 on the dyno and fit into any chassis made for the 351.

Right, you could bolt them on but you couldn't (at least when I was looking) find an intake manifold to fit.

Sometimes you just have to get the mill and the welder out. (It's been almost twenty years since I made an intake. I would just be burning holes in it these days without a lot of practice.)

Well....now that you've got the car, I guess you'll be getting into the private eye business....

I'll chip in for a pair of chandeliers to mount on the front fenders.

Wow, that's sweeeeet...

So you'd just bolt it together and weld up the empty spots?
