Single turbo size for 460 street and strip

Trying to find best size turbo. I have a 460 .030 over , stock internal balance crank , h beams and flat tops right now. A429 heads,victor 4150 intake .small Herbert solid roller. Engine makes 550hp n/a . Engine is pulled and ready for dish pistons and cam swap. My goals are 700-1000 hp on e85,probably 6000-6500rpm max. Hopefully a blow through carb or possibly efi.All this with a TH400 (sorry) in 91 Foxbody . Turbos are new to me and I’ve been doing a lot of searching for information. Thinking possibly s480 single. Need Help thanks

Poke around here.
