Once the Hydrovac gets into the act, you should have plenty of pedal. Right now, you've got about the same situation as any other power brake without vacuum assist, having to push the fluid through the system with no boost. The hydrovac is actually a second master cylinder operated by the vacuum chamber, which uses the main master cylinder as a trigger unit. In case of a loss of vacuum, you have to push both master cylinders with foot pressure, which will lower the pedal considerably. Get it running, and I think you'll be pleasantly surprised with the difference in pedal height.
