Without me running 110 I wouldn't want to run 15 degrees base, but it really likes it, never pings, detonates, hesitates.
I'm planning a trip to Oklahoma next year, then will be cutting east and I'm going to stop by this shop address to see who is still there/what they know. Then headed to the POCI convention after.

As discussed I have nice details that include pictures of the restoration done 30 years again. Also have maintenance records but unfortunately no details on the engine build. Would like to know what cam was used however at this point my judgement is something similar to a 744 cam. My engine likes where the timing is set now and dwell angle is set at 30. Idle is good but can be better, ignition, vacuum leaks and carburetors have been sorted out. I’m running blended non ethanol gas that gives me around 98 octane. Next thing will be to verify all 16 valves are opening (approximately) the same amount. Although unlikely could have a worn lob or two, more likely I will find it out of adjustment. Also don’t believe your engine would be looking for 110, worked at a gas station as a kid and we sold Sunoco custom blend thinking 8 grades and 260 would bring you in at 98 octane.
