chevy front power brakes to hydroboost

[MonsterBIlly]

I currently have the chevy front brake conversion. I just don't have enough consistent stopping power. So i am wanting to go hydroboost.
I do have factory power steering. What all do i need to complete the conversion.
Do i need a new master cylinder too?
Will I need new brake lines to my prop valve?
I am thinking i may just need the hydro boost unit, adapter and lines...
I would think that my current set up would work better but i guess not. My Fitech shows I have good vacuum but my brakes are inconsistent.

For the most part the hydro unit and lines to and from the ps system. The brake lines to the frame should work or possibly need adapters if you change mc's. The only snag I see is a stock eb ps pump may not handle the load especially if you have big tires. You might want to swap to a Saginaw dual return pump.
