Personally, I would much rather have a seasoned iron block, that has been thoroughly measured and tested, than I would a new iron block. No two ways about it.
And I would be the polar opposite, assuming you can find a new or used Genesis iron block. I believe most of Barry R's Engine Masters FE builds have used the Genesis iron block. Though it sounds like they're unavailable at this time.
When I first started looking for a nice used FE block, all I saw was junk, near junk and repaired junk. Blech.
As for the Coyote engine in your Cobra (or a 428 for that matter), if you're trying to replicate this experience:
Cobra Make, Engine: ERA #732, 428FE (447 CID), TKO600, Solid Flat Tappet Cam, Tons of Aluminum

Hmmm, I do not know how difficult it is to now get one's hands on a really nice, unmolested 428 block with the crank saddle webbing, suitable for boring out a bit. Eight years ago, it took my builder about six to eight weeks, IIRC, to find something that made us happy. Brent would know better than I on how hard it is now. Maybe you really can't do it anymore except at a cost prohibitive price. And maybe it's just not worth the builder's time to screw with the search anymore -- that's a real possibility.
