I'm going to this up, with better data.
My combo- 406" B engine mildly ported RPM heads 9.7:1 cr, Comp Cams thumper- the baby thumper 227/241 .518/.504" lift with 1.6 rockers 107lsa and a Offy tunnel ram. The previous jets listed were VEERRRy lean. The final jetting ended up .92 primary .89 secondary .52/.62 metering rods.




Current jetting is .95 on the primaries with an old set of .60/.70 metering rods and .83 on the secondaries.

With the O2 gauge this is very close with some minor tuning needed with the metering springs to dial in the cruise a touch better. Car just screams to beat the band now, rear gear change coming up next.
