4.7L bellhousing bolt pattern

No clue but I can attest to one thing. With the 4.7's craptasstic reputation for gas mileage, you can probably get better from an LA360, and no doubt from a 318.

I've never had one, but I have friends who do and they claim the gas mileage is fantastic. Some links for info and the claim is that the bellhousing is similar.
