Although I had heard there was no room left to stroke or bore the motor out. I wonder if that is a new block. Then again I heard the motor would never handle boost, and here we are.

I remember reading that it would be very difficult to increase the bore. I don't recall reading that the stroke couldn't be increased.

Or a helluva "I dont give a **** if the wrist pin is making love to the second compression ring" stroker.
I guess there still are some stroker kits for a standard bore pushrod 302 that nip on 351 CID for you know, when 347 CID is not enough
I could dig a tall deck coyote, it is Ford's prefered method of adding displacement and what a cool why to make a next gen GT500
Crazy I know, why would Ford just make a special engine just for the the top dog Mustang

Well, I used to work major repair in the plant making 351W in the late 80s; and without the deck height you would have to stroke out nearly 1/2" on the crank (ie a 351 crank) and even by shifting the wrist pin you're coming dangerously close to the piston skirts emerging from the bottom of the cylinder bore. Remember what you don't stroke up (because of a limited deck height), you stroke down. It would never take the kind of revs that the Coyote thrives on, the piston head distortion would be horrendous.

I'm no Ford engineer of course. But I was under the impression that the 5.0 is basically a stroked 4.6 with awesome heads. One of Ford's stipulations to the engineers when they began designing this block was that it has to be made on the same machines as the 4.6. That is why the mounts and bellhousing pattern are the same. And along that line of thinking, I read there was no room left to stroke the engine further. And that in fact, the cylinder sleeves were already extended to handle the stock stroke. It's also completely possible that I am entirely incorrect, so take this post with a grain of salt.
