I have power disc brakes, pcv line, distributer and modulator lines which all need vacuum. I have a WIEAND dual four tunnel ram with brand new 450 holley carbs, manual secondary.

I was wondering if I should tap a fitting into the rear for the brake booster, or would the carb vacuum fittings provide enough vacuum for all accessories? I don't want to put the spacers under them with vacuum fittings, or get an electric pump.......anybody else dealt with this before?

FYI, it is a 72 Camino, bone stock 402, highway gears, no stall, just want to have the 'look'.......I figured vacuum is vacuum, either GM or Mopar! Thanks for any help.
