318 4 bbl install and linkage questions

I changed from 2 bbl to 4 bbl also. I've made a throttle cable bracket that fixed the throttle cable and I extended the throttle pressure linkage that is hooked up to the carb. I have 0.24 inch (6mm) to much at the throttle pressure linkage rod to throttle stud at WOT. Everything else is right where it should be but I have read that the 2 bbl have more travel then the 4 bbl so the geometry is probably diffrent. Does anybody have any idea to solve the problem without changing to 4 bbl bracket or Lokar cable?
Thanks FABO
