I just installed a victor intake and 750 holley double pumper on my 67 fairlane with a 347 stroker. i pulled off the old linkage and put a straight bar from the gas peddle bar to the carb. when i push the gas peddle to full throttle the carb only opens the primaries and barely opens the secondaries. i still have about another inch to go before the secondaries will fully open, but i have no more peddle for this. does anyone have any idea how i can get the secondaries to open or if there is some type of special linkage that i can buy for this?
