dialing my 318 in finally!
We're really taking some "fine" tuning issues here. A lot of your numbers look decent, especially as far as the vacuum with that cam. I'm wondering how lean you are on the primary side with the drilled plates...That could be a issue, especially at the 1.7/8 A/F adjustment and still acting lean. I'd prefer the float levels a little lower, but a lean condition can also require the higher adjustment. My personal liking would be a primary PV in the 8.5" range from the info you've given. I may disagree a little with "cracked" as far as the timing curve, considering you seem to have a pretty high compression ratio. As far as the vac advance, i'd get it running right without that first, and then try to add it later in the tune.
