Default What should I expect?

I ordered an LS6 intake and duals w/Dynomax Bullets from Texas Speed yesterday and I got a ported throttle body to go with it, I was wondering in anyone had any idea what I should expect from my setup now. Here's what I've got:

383 w/Eagle crank, rods, JE pistons (11.5 cr)
Hotcam w/1.8 rockers, Ported stock heads w/bigger valves
K&N, Lid, Smooth Bellow, MSD's, NGK TR6's
Kook's 1 3/4" LT's, Kook's ORY, stock catback with a Flowmaster
Yank SS3800, 3.73's

Last time I dyno'd 360rwhp,378rwtq. I'm hoping to pick up to around 400/400, Is that too much to hope for? I'm thinking that the step down to the 3" pipe and Flowmaster was killing my car, and hopefully this winter I'm going to tear down to get a bigger cam, most likely a MS3.

Any ideas? I know that the Flowmaster and Hotcam is a bad idea in a 383, but I had to build the motor because it spun some bearings as soon as I got it and I ran out of cash, had to go with what I had, not what I wanted at the time.

You have a 383 with a ls1 intake and a chokemaster CB That moter is hating life right now. I would say with the intake and true dual setup you should be over the 400/400 mark.

I'm hoping that you all are right. Nothing sucks more than running out of money in the middle of a project. I think that might cause some of the issues that I have with idle right now. It will act fine for a while, then go through spells of surging, usually only when I'm in a place with a lot of people around, making me feel like an idiot.

After you get done with the swap post up some results, I think you'll be happy with the outcome.

I'll do that for sure. You know how they always adveritse gains by going from the worst possible setup to the new product? I might be the new posterchild for the Rumbler X.
