Chevy 350 4 bolt main Max HP

[77ChevySharkBite]

So I have recently found out thankfully that my motor isn't a Chevy 350 its a Chevy 305 thats a 2 bolt main, which thankfully I found all this out before I started dropping serious cash trying to get mad torque and hp out of it.

What my question is, is what is the Max HP you can get out of a Chevy 350 4 bolt main, safely and still if I wanted to have it as a daily driver I could. Note this its not an LS1 motor its a Crate Chevy 350. Any advice or help will be perfect just trying to make a game plan for my motor that I'm going to have to buy.
