Lunati, Ford Performance Parts(not my first choice). Do you have a 5.0 or a 4.6? I'm assuming that you have a 5.0, seeing as how that 4.6s don't really have a whole lot of choices. YOur best bet is to figure out what you will be doing with the motor first. i.e., Blower, turbo, N2O, or NA. then you need to decide which displacement you want. For my money, you can't go wrong with a 331. You get the power of a 347 with the ring life of a 306. Don't let anyone tell you that a 347 gets good ring life either. The piston rings, no matter how you look at it are going to wear out long before a 331. The piston has greater side loading in a 347 than in a 331, not to say that a 331 doesn't have issues with this either.
From my experiance, you'll get roughly 60K miles out of a 347 ring set and about 80K out of the 331.
Just my opinion. Frankly, for the amount of money you will be spending anyway, why not try to find a 351 block and build a 392 or a 408. You'll still have the ring issues but with the power you'll generate, who cares?
Wow, I just wrote a book huh? Sorry dude. If you need some help later on making a decision, feel free to call or email me. If you need my phone number, just PM me and I'll give it to you.
