Depending on application (tranny, heads, cam, etc...), anywhere between 430 and 480 rwhp/rwtq.
The big benefit of a stroker is that it give you a much better curve over a H/C setup.
I hope to see 445rwhp/440rwtq on my 382 stroker (street setup with a very mild 224/.560/112+4 cam).

With a stroker, you keep your old block with a just a .005 clean-up to obtain a 383 (3.903x4.000). Your stock heads can be ported (stage II). You only need bigger heads if you do an all-bore motor (stage III).
Basically a stroker package consist of forged crank, rods and pistons.

Can you re-use any stock parts like Heads, Intake, Etc? Sorry to steal this guys thread but maybe he has the same questions..
You can have you stock LS1 heads ported with bigger valves or buy some LS6 heads and have them ported as well (ported LS6 heads should give you 20rwhp over ported LS1 heads).
You must change your intake. With a stroker, an LS1 intake is a big restriction. At least, go with an LS6 intake or the new FAST intake with 78mm throttle body (more pricey but worth it with bigger cubes).
Other things to consider: 30lbs injectors, double-row timing chain, heavy duty oil pump, hardened pushrods... and of course a 12 bolts
As for the cam, most people here will go with 230 to 240 durations with 112 lsa for M6 and 114 for A4. It all depend on the applications. As I stated before, my cam will be very tiny (224/.560/112) compared to others but I'm after low and mid-range torque, reliability and driveability as my car is my daily driver. If you're looking for peak numbers, go with higher duration cams.

A Forged bottom end? What exactly does that mean? Wouldnt mind after the motor is built to throw a SC on..

I am going with a 385 stroker. No dropped sleeves and light alum block 
With a six speed and stock rear should be anywhere from ~450/450 RWHP/RWTQ up to ~500RWHP/480RWTQ depending on cam, intake, exhaust combo.

The forging process compress the metal under very high pressure, making it more resistant. While the stock bottom end of an engine is good for "only" 600hp, a forged bottom end is supposed to be good for over 900hp!!!
And with a supercharged 383, you will see well over 600hp at the crank!
