Turbo Guys I need your help ASAP

[au03z71]

Here's what I have... 385 ci roller stroker with Vortec heads, originally built for natural aspiration but I've caught the forced induction bug. The more research I do the more I want to go turbo. I'm going to upgrade to forged h-beam rods, forged dish pistons, and possibly a new forged crank... but I have found a set of T3/T4 hybrids (1.32 A/R hot side, .42 compressor side) that I can pick up for $300. My question is, are these too small? I am afraid that they'll spool too quickly and choke out on the top end. The motor is in a 72' SWB c-10. I'm looking to get 600hp + at the wheels just to have fun on the street and occasionally take to the 1/8th mile. It will live in the 3500-4500 rpm range on the street and seldom see over 5500 rpm... Help me out, I need to move quickly if I want these turbos... thanks!
