Hydroboost?

[78MC-BBC]

i am currently using the stock hydroboost system out of an 85 buick grand national, i did a complete conversion to the monte carlo since the big block does not make a lot of vacuum and i like having brakes that work expecially with the 13" C5 vette brakes up front and 12" LS1 brakes out back.

here is what i used

85 GN parts
hydroboost assmebly $120 new
hydroboost brake pedal different than vacuum one $free local guy
Hydroboost power sttering pump $85
Hydroboost master cylinder diff. than vacuum $20

Summit racing
Russel braided stainless power steering lines & fittings $120
Synthetic power steering fluid $5

I am using a custom serpentine belt setup off a S10 pickup
so i am using the S10 serptentin pulley on the pump also

did you have to change your prop. valve?
what do you have for rear brakes?
