Re: need some help breaking the 8s
changing from 69 jet to a 67 jet in the primary led to .2 slower times. But it runs better on the street. Is it possible to have to lean the primary jets and richen the secondaries? or should I just change it back?

Did you change the jets at the track and do back to back runs? If not and the runs were on different days, then I wouldnt go by those results.

Did you get the 60ft times?

leaning out the primarys helped driveability, but leaned out the overall mixture enough to kill some power..... Now richen up the secondaries a little and see what happens.... Now you will get full power and better fuel economy...
