How much rwhp do you think my 01 Z would make with a 383 w/ full exhuast and a CAI?

I'm doing the engine swap and plan on adding a twin turbo but just want to see what i could make without the turbo.

I'm using the stock ls6 heads and cam stock throttle body and intake manifold. I have 1 7/8 kooks headers w/ off road x pipe and b&b bullets catback. I got the Halltech Stinger II CAI no aftermarket underdrive pully and compression will probably be still about 10.5:1 and i'm at sea level. I'm just looking for estimated numbers.

Adam,with the stock (OEM) LS6 Heads,cam,intake and TB,your restricting yourself and the motor and leaving boatloads of HP/TQ on the table.Porting the heads and TB,going much bigger on the cam will net BIG HP/TQ gains.I'm thinking with the OEM parts you'll be in the 425-435 rwhp area.Could be more depends on a wide range of variables.jerry
