Default 418ci lq9 block ... want to boost??

whats up...im new to the forum and the whole ls based engines. i recently traded my bbc drag car for a ls based "street car". it is a 2000 camaro ss with a 418ci motor in it. it currently has a 2 stage nos plate system on it but i want to get it boosted. Engine is a 418 with a LQ9 iron block bored 30 over, fully blue prited. And a balanced eagle 4.1" crank and eagle 6.2 inch Rods Custom (Arias) Piston for spray, L92 Heads Fully Ported by Felber Race Engineering, Dual springs, Stainless valves. Hydraulic Lifters.1.7 Roller Rockers Ported oil pump Cam 248/254 .615/.623 -110 lsa Eldelbrock single plane intake, 950 holley carb, msd 6ls, and an Aeromotive A1000 fuel pump.
Im just wondering what kinda of hp a stock block will support and what is a good turbo to go with. i plan on making my own headers and piping just need a good turbo/carb setup. I'd like to make as close to 1000+ hp as possiable. the car currently runs 6.60's in the 1/8.. N/A...at 3200lbs... have not yet sprayed the car yet. any hlep guys would be great... thanks

Drop the compression to 8.5-9.0, change the cam, use around a 88mm single or twin 62's.

what pistons and rings are in it? I would hate to tank a good engine just because it is built and forged and you think it should be able to handle the power. Also you might start pushing head gaskets out at that power level with your heads.

Way too much stroke for an LQ9.
