Don't take this personal, but seeing that you are new to the board, and maybe turbo Buicks [?], you ask a question, and then "debate the answers.
We build lots of "new" blocks, Dart, indy, World, TA, and they actually take MORE machine time than a used block.
First, when a customer spends thousands of dollars to build a performance engine, ALL the details must be completely checked and brought within very close tolerances. New blocks are not machined to finish specs, as the customer and shop determine this.
Like was stated, $2000 is just a start on a 109 block, add things like a stroker, stage or alum block, oiling system mods, and it goes up fast from there.
You have a goal of mid-9's, so in a GN this equates to at least 900 HP. To do this consistently and reliably, you need to have about 1000 HP available.
This will need more than $2K worth of block work.
Opinions and comments are cheap, want some true $$$$ figures, ask the guys that have been there - mid 9's that is!.
