Which turbo for a 500hp 273?

I was thinking of an air wolf headed 360 for my 65 Cuda and looking for 500hp/500lbs-ft, but as I'm dumping $120 for just over 200 miles in my 5.9l Jeep, lucky I live a only couple of miles from work, I don't really need another pig on gas also got 1980 Bronco with a 400.

So I'm think of keeping the 273 and turbo it, for now I'll build the engine and add a turbo/s latter, I was figuring .30 over custom forged flat top piston zero decked and a .35 quench and scat rods added to the factory forged crank, ported out 302 heads and cc'd to give a 9:1cr and a highlift 262ish cam and a airgap intake and for now stock manifolds until the turbo swap. Also before the turbo swap I want to EFI and 5 speed.

I've read a build on a stock 2v ford 4.6l and $500 eBay t76 turbo 9.6 boost got 500hp, I'm assuming that would work with my 273? Looking for pump gas 500/500 hp/tq engine, also what RPM do I want the turbo/s start to come in and at max boost, I'm thinking peak power is gonna be 6000-65000 and a 7000 redline.
