2)556hp Cadillac 6.2L LSA(forged steel crank/cast hyper pistons/forged PM rods,,
3)505 hp 7.0L LS7 forged 4140 steel crank/cast hyper pistons/forged steel titanium rods.

Using your logic, all aftermarket manufacturers that produce a cast crank will experience breakage, simply because it is made of metal that is cast in a casting, vs. being forged into shape?

I could have posted pages of issues with Eagle cranks.

Look at the 4340 forged unit, it was out 1-2 thou. from center to edge of the main bearing surface. Thats horrible, but typical of many products manufactured these days.

sorry, I figure most people that are building warmed over engines blow right past the cast parts, otherwise why not use a g.m./ford part as there are millions of them..
and frankly I'd rather a crank that wasn't finish ground.
maybe it me, but if I'm buying a new crank, it's a forged one.
there also is a reason eagle/scat/etc are half the cost of other cranks.
