That's a big car to be fwd. I would think the bolt patter on the block would be the same, since the main objective with the modular blocks were the keep them as similar as possible. I know there are some differences in the crank bolt pattern though with the flywheel bolts.
They are different. 
Bummer.

"4.6L DOHC engines have come with blocks cast in both iron and aluminum. You can find the aluminum blocks in Mustang Cobra's up to year 2002, Lincoln Continental, Lincoln Mark Series and the Lincoln Aviator. These blocks are cast by Teksid in Italy for Ford. All of the aluminum engines are assembled at the Romeo plant. No SOHC engines have ever been cast in aluminum, although the blocks are generally interchangeable between the DOHC and SOHC. The only exception to this is the Continental engine which is front wheel drive. This block will not work in rear wheel drive vehicles. One of the motor mounts is not drilled, the bell housing is different to allow mating up to the transaxel, the oil filter is located on the opposite side of the block, the front cover and accessories are different. The oil pan has a front sump so this may help with some swaps that require a front sump. If you get stuck with one of these engines, you can still use all of the internal parts, cylinder heads and intake. These parts will bolt up to an iron or aluminum rear wheel drive block. Be sure to evaluate the time and expense associated with this kind of swap, all of the necessary parts needed to complete this conversion will add up quick."
But it looks like you could add the good heads to a garden variety Mustang block.
