| I had pretty much figured on problems with the power brakes so decided to stick with manual brakes early into the build. I spent a few hours playing with different springs in the vacuum advance and found one that works. Took quite a bit of time driving at different rpm's and watching the vacuum gauge to find out just what was going on. I also found that I had to install a 4.5 power valve on the holley carb to eliminate a slight bog during acceleration at lower rpm's due to the power valve fluttering because of low vaccum. I lucked out by installing a TCI reverse pattern manual valve body modification in the C-6 as there is no way the tranny would have shifted correctly. I pretty much eliminated all vacuum leaks even on the carb shafts, I did rebuild the carb and replace the teflon strips on the shafts. Great cam for a car that will not be daily driven and more of a weekend warrior ride, though im thinking that steeper gears are in the near future. Thanks man for all the help and info! |
