And what the heck is wrong with doing research on various engine families and asking a lot of questions? Sure, some of us know that an all-aluminum FE is the best and only choice for a 427 Cobra, notwithstanding some engine builders not being able to handle machining them not to leak, but there are others who just don't know which is best (all-aluminum FE's), so they ask questions.
When did we become so intolerant? You would think there's a political rally around here.

I will say this.....if the aftermarket FE block manufacturers don't get their QC under control, I'm gonna skip building FE's altogether, aluminum or cast iron.
Barry just had a brand new block lose oil pressure while priming the oil pump on the dyno and found out that a main oil passage had been drilled through.....so it was just bleeding out internally.
I've had brand new blocks that needed sleeves.
I've had brand new blocks that needed lifter bore sleeves because of porosity.
There are some cast iron blocks floating around where the lifter bores are not finish-drilled all the way through, so there's a step at the bottom.
It's really beginning to not be worth it. When you have a back log of orders and you have to pull one off the dyno to fix something or you don't find something that should have been done until the block is finished and painted, it just pushes everything back.
Not to mention that I can make the same horsepower with a SBF with 50 less cubic inches....

For me, if all the engine builders are having trouble with the new FE blocks, iron or alloy, then before I stick a SBF in my Cobra, I'd probably look at the Aussie formula for the LS-series of Chevy engines.
For me, if the decision has been made NOT to go with an FE in a 427 Cobra, then I'd go with the easiest, fastest and most reliable modern FI solution that's readily available. If that's a Chevy or Mopar, then so be it.
But I don't want to hear any complaints, moaning and whining about the parts this or the parts that from either the engine or car builder. I want near-Toyota Camry reliability.

Brent, does that include the higher dollar Shelby FE, and the BBM ?

Ummm... I'm so confused. 
I thought you told the bloke to rack off.
...not to be rude, but does it really matter?
You're unlikely to be purchasing one of these, last I recall they were out of stock.
In any case, I think I was pushing for you to get an Fe early, but that's because that's what I like. The more I think about it, perhaps you're better off with 385 series.
By the sound of it, you and your build already seem very much committed to that path. So it's likely your build would proceed quicker and smoother with a 385 series. You might even still be alive to enjoy it.
Further if the worse imaginable were to happen, repair costs would be more manageable for you.
It's a win win for you. Cheap power, easier build option, and if it's important to you, it's still a Ford and a "big block".
Now hence forth a search accordingly.

Dang I just talked to Lance a few hours ago, at the London Car Show. I never thought to ask him about new aftermarket FE blocks. I did ask if finding good original blocks is hard to do. My local supply of dozens of 390 and some 428 FE blocks went, when the scrap metal prices sky rocketed a few years back. The guy cashed in the entire yard and retired. Lance said that original FE blocks are getting harder to find and are costing more.
I'm not sure I trust these 50 yr old blocks, and the new are too costly. Now quality is questionable on top of that. How much longer can the FE dominate the Cobra Pack?
