2015 Ford Mustang engine and underhood spied for first time

The 4.6 aluminum block is no longer produced and I don't see them going to a heavy cast iron block just so they can go backwards in engine design.

If anything they'll simply strengthen the Coyote.

You can't add surface area between bores.

That said you can obviously boost a Coyote and as I said prior, possible but not probable.
