Ford SVO engineers did that a couple of years ago with a later model and they had trouble getting it faster than the 12's because of no traction. Just way too much torque. You want different, use the 5.4. Quick, go with a small block. Know a guy out in York, PA who was running in the 11's with a 347 and a KB. Completly streetable.

Edit: Found the link to the SVO build - interesting read.
