12.0 on 91 octane. Iron heads... Gotta keep the temps down to below 180 and use the clutch to shut it off. 34 degrees in by 2800 12 degrees static. light silver springs in the MSD. Vacuum is 5 inches +/- 1/2 inch so the power valves are 2.5 inchers. Watch your distributor curve and listen carefully for preignition.
It runs a little fat but better fat than lean, I went up to 63's in the primary's and the secondarys are standard with whatever the list 9773 4260's (450 cfm) came with.
I tried 660 mechanical secondary carbs but it was like driving a guided missle. I might get those back on and sort them out a little more they should push the HP to 575 or so.
