What kind of horsepower to expect 383 build

I will be running it. I wound up getting pulled away from it today but hopefully will be lowering the engine in tomorrow. Still a few small details to work out aka pullys and what not but once the motor is in the start will come soon. Here is a pic of the engine sitting ready in my garage. Excuse the mess.

The carb is just there to block the hole in the intake. Not the one I plan to run.
