Edelbrock casting SB/BB Chevy blocks

My question is the market is already flooded with cheap 350 cores. Now how cheap they may become (with or without the addition of a new virgin casting) seems to still go back to the LS craze. These are the new SB's from Chevy, can get them cheap at yards out of trucks already and the power stock is very good with minimal upgrades as most will stick with EFI. I just dont see it. Im not a stockholder and probably wont become one.
