Approx. how much rwhp will an SC-Trim ad?

If you click the link in my sig you can see all my mods. But here is the run down for those who are lazy :p

Edelbrock performer heads
Edelbrock performer intake
Crane 2040 cam (e-cam)
All other supporting mods

I have plans to ad an sc-trim in the future. I will be starting with just a stock sc-trim, meaning no power pipe or smaller pulley. I want to be in the 350rwhp for my daily driven street car. As of now I figure I'm right around 280rwhp untuned. Would a box stock sc-trim with a good tune put me in the 350rwhp range? Also, what other supporting mods will I need? Right now I have 24# injectors, so I know I'll have to go with at least 30#. I also have a C&L 76mm maf which I heard are not good with blowers, so I'll probably upgrade to a better one as well. I only want 350-ish to the wheels because the car is my daily driver and I don't want to push my stock block too much... Will a stock sc-trim get the job done?
 
roughly, about 10hp per lb of bewst.........can get alot different with other factors, like if you had a cam specifically designed for your combo and boost......then maybe 15hp+/lb of boost.......not to mention what kind of fuel you have a available to you, and how ragged edge you wanna go on the tune....... I have got a max of 140rwhp with 10lbs of s trim on 91 octane fuel. thats 14hp/lb for the lazy people :)
