Will idle good in gear only after fully warmed up ( stock converter ). Otherwise, I have feather the throttle while putting it in gear, then if it doesn't stall it's OK.
This sounds like a little more choke and fast idle would be at least part of the answer.
You should have to enrich the carb when the engine is not up to temperature.
Try this test, open the idle mix screws 1/2 or 3/4 turn each. Does the rpm go up? Does it go into gear with a significant drop in rpm?
Agree maybe up to 16 degrees base timing might appropriate with that cam. 14 should be OK though. This is assuming vac advance is not hooked to manifold vacuum. With that much manifold vac on top of your base timing, that would put the idle timing way high, which would run lean and OK in neutral, but die when put in gear. Either plug or use ported vac for now. Or if you're going to use manifold vac, set idle timing with it hooked up. IMO it's trickier to do it that way with a performance cam, but there's more than one way to skin this cat.
