Just thinking about this. Maybe the 5.0 Coyote's replacement will be the new 5.2L V8 that's going into the GT350R. Perhaps the 5.2L V8 will debut in the 2016 Mustang.

If they do that, I would bet they don't include the flat plane crank. Of course this would also mean no new Boss 302s. They'd have to be a Boss 317s!

The "new" 5.2 is just the coyote with a different rotating assembly... flat plane crank stroked to 5.2L, it may have different heads and different intake, but I almost guarantee you the block is the same.

I could swear I've read that the architecture is similar, but the 5.2 get's it's own block. I don't think you can make a Voodoo engine out of a Coyote by simply swapping the rotating assembly.

I think the increase in torque from the 5.2L V8 is necessary to make the heavy S550 platform competitive with the Camaro.

2. Coyote foundation, but not a parts-bin build.
The engine may have been birthed from the same architecture as the 435-hp Coyote 5.0 from the new Mustang GT, but nearly everything has been replaced. The new 5.2-liter engine has its own block casting, new crankshaft (duh), new pistons, new connecting rods, new heads, new cams, new intake, new oil pan, and a new harmonic balancer to smooth out the flat-plane’s inherently tricky vibrations. The only carry-overs from the Coyote 5.0 are hangers-on such as the alternator and starter and a few small components in the valvetrain. The 5.2 also utilizes plasma-transferred wire-arc cylinder coatings like the outgoing GT500.

The single biggest challenge in creating a long-stroke flat-plane crank (FPC) V8 like the Voodoo is vibration (specifically a pronounced second-order lateral shake). So, given its huge-for-a-FPC 92.7 mm stroke, it's no surprise that quelling the Voodoo's vibes was one of Ford's primary development tasks.

For reference, the 5.0 also has a 92.7 mm stroke, meaning that the new crank is NOT a stroker crank and that all of the extra 0.2L displacement came via a bigger bore.

That's the article I remember reading. Good info!

Another significant detail seems to be the finish on the cylinder bores. I think the 5.0 has steel liners.

you will not see the 5.2L in anything but the GT350 and GT350R. I am sure Ford will still surprise with the upcoming Mach 1.
