I looked up some Jeep timing for the 360 and came up with a lot of differant numbers between 75 up from 2.5 advance to 10 advance, the one that goes with the graph you show is 10 or 15 at altitude. Bottom line is none were higher then around 38 degrees total. One 304 for 49 state was 44.5 while CA was 38.

So total of 38, then some distributor machine test numbers, mechanical advance max of 16 and vacuum advance max of 8.5.
16+8.5=24.5 from total of 38 = 13.5 base

Which is equivilent to just about any engine from that time from factory to meet emmissions = the timing table in the bin I gave him is well within safety margins of me trying to help while not there in person = plenty of room to add some timing.

= run the bin as is, don't worry about BLM right now and don't worry about idle. Get some data. With your cam and altitude we can work on idle with spark and fuel.

Start data fully warmed up and driven a little.
