Got the manifolds reinstalled but still have a slight exhaust leak at the exhaust pipe/manifold connection (we can get this resolved). With engine operable again we confirmed the charging system was not working. Took alternator and external voltage regulator to local Woods Battery - turns out it's a Delco alternator and regulator, and the regulator was bad but alternator was fine, putting out 60 amps. Was really cheap to replace the regulator. Charging system works fine now, over 13 volts on the dash gauge. Also removed the oil pressure light from the wiring and installed it as the ignition light, much more important since we also have an oil pressure gauge.
Here's some video of Ray driving the car:
It's got a significant hesitation on acceleration, probably carb related. We've checked dwell and ignition timing, both on spec. Will order new diaphragms for carbs, typical failure for Stromberg carburetors. Cooling system works fine, stays cool, had a few small leaks on heater hoses that were resolved by adjusting hose clamps. Oil pressure continues to look good.
Took time to clean up remaining wiring in engine compartment now that we've got the charging system working. Also completed installation of demister/heater hoses. Ray did a nice job of cleaning up and painting the valve cover and air cleaner:
