Re: How hot do Big Blocks normally run?

I rode in a 70 Vette in Reno back 30 years ago. The gauge hit 245. It was nerve racking.
With 34 total timing there’s a chance you only have 8 initial.
More initial will help it run cooler.
You could try plugging your vac advance back up to a manifold vac source.
