Hi, thanks for answer. Im driving Ngk 6 now, the carb is one step leaner with 63-47 metering rod and the original 5hg orange feather,i have 18hg inch vacuum at idle. I get the FBOdistributor working properly now, its running better with that, no misses at idle and a rock steady timing mark, better with vacuum advance for the street. It looks rich, this big Mopar seems to not want so much fuel😃


Factory metering rod is .065x.052

If you are running .063x.047 metering rods with the factory jets .104

You are over 8% RICHER from stock
