Actually, have it all on the dyno sheets. It yes it has PVs in the front and made best power (there at 2300' elevation 2000' air) with 68/76 jetting, and had to drill our own high speed air bleeds to .040" to get A/F to come around. That was with C-12 fuel,, your particular s.g. of fuel, altitude, and setup may be very different. As I recall they come out of the box pig pfhat at 74/84 jetting.
The dyno was reading a consistant difference in A/f from the collector mounted O2 sensors, but EGT's were within 50° across all 8 at best power. Have to believe it was some annomoly with the O2's or those particular O2's reacting to the massive doses of lead they have seen on Larry dyno.
