No I put the stock weights back and I'm checking their advance curve so I have a baseline to make adjustments to. I have a spring kit and an adjustable vacuum advance, so I have full adjustability. It's not pinging that I know of, but under load the exhaust tends to bang against the bottom of the floorboards so it makes it hard to hear for sure. But it's stock settings, so it should be nowhere close on the 8.1:1 CR with 87 octane.
I don't have a tach in the dash, so I don't know what it reads at 70mph. But the math says:
(70mph x 2.73 ratio x 336) / 26.5" tire diameter = 2,423rpm
