Performance Chevy 305 (Don't hate me)

So i just finished rebuilding my first engine, its a 1984 Chevy 305, don't hate me for that, haha. Anyway i am running an 11:1 compression ratio and a mild cam, how much horse power can i expect to get out of it?

Cam specs:

Intake Duration at 050 inch Lift: 234

Exhaust Duration at 050 inch Lift: 244

Advertised Intake Duration: 292

Advertised Exhaust Duration: 302.

Intake Valve Lift with Factory Rocker Arm Ratio: 0.488 in.


Exhaust Valve Lift with Factory Rocker Arm Ratio: 0.510 in.

Lobe Separation Angle: 114

I am also using an intake and Quadrajet carb off a late 70s Chevy 400

I just got it mounted on the break-in stand and will be firing it up one day soon!
