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. The engine made 472 hp/489 ft/lbs with plenty of room for tuning. The secondary air valves were too loose and we made no timing adjustments- it was ran with 35 degrees total. The fuel curve was deemed ok by Brian @ IMM and it was a long hot day in Indio, so I decided that was enough. Once it's in the car with the exhaust and my headers I'll dial it in- with the broadband sensor.
