I would make sure you run a big oil cooler and I think you'll be fine. Filling can cause overheating because if your cooling system is marginal and you remove a gallon of cooling capacity it isn't marginal anymore it's to small. Now that you know plan a bigger radiator and an oil cooler and you will be fine. When I did it I was listening to a local expert and ran half filled block like you have and aluminium rods because he sold them to me. Fast forward 30 years and I understand a lot of what went wrong there. It's better someone told you now then finding out like I did. Anyone trying to build a turboed v8 and is actually buying parts isn't rice. We can help just don't get offended to easy some of us jest a lot harder then others but it is all in fun.

I run the biggest eBay oil cooler I could find with it's own cooling fan. I live in Texas it get 110 or around all summer so I need all the cooling help I can get. I had a billet s480 t4 on my lsx376 and I'm sure I was around 1000 rwhp since 9 pounds was 770 and I had turned it up to 18 pounds after a fuel pump upgrade. I think you should make your goals. Good luck.
I acknowledge that I didn't understand the question...However the whole attracting "fast and the furious" comment was unnecessary. I have been in the car scene for a very long time and have had several fast cars. Just because I wasn't aware of what the filling of the block meant? I haven't ever had a block filled. I happened to purchase a motor and it came with the receipts...I didn't have a clue when I read it what "filled" meant. Guess I am a loser, newb, fast and the furious ricer. 
Out of curiosity... what kind of power will a 1/2 filled LSx iron block hold and at what power level should you consider it?
I like the idea of an oil cooler here as well under the take all the help you can get theme... depending on plans you might not need it though, first oil change will tell a story if you don't run an oil temp gauge as will coolant temp.

Practical limits of an OEM BBC is roughly 1200 and even then many find the mains walking.
So did the shop really need to fill the OP's block if the stated limit was ~1000 hp?
I'm asking because at some point I want to move my SBC/NOS to a LSx/Turbo, this will happen after my current JY build.

who filled the block with rice?? Hard blok is what most use, Moroso has a competing product.
I have only used HB, Hard to know exactly what it is but it is less than $100 and surprisingly lightweight.
There are some specialty epoxy mixes like Devcon too but they cost more. I read somewhere that some folks throw steel shot in a the epoxy, the thinking is steel shot expands and contracts with the heat to ensure the stability of the fill remains constant... not real sure how you balance the shot distribution... maybe it is more shot than epoxy??
