I don't have a 4.6, but my buddy just got one. I've heard in the past that what changed the displacment wasn't cylinder diameter, but rather a shorter stroke and that being what made it a 281 vs a 302. Is this accurate-ish? Obviously there are differences like DOHC on the new ones, what I'm concerned about is the displacement... On the GT's.
