your motor will always run better at idle with a higher advance. it will also pull water in from the exhaust and hydrolock.
what did you set the dwell to on the points prior to the timing?

I would pull the drives and paint them ASAFP.
Annual maintenance on moored boats is painting the drives, don't the zincs and doing a bottom job
Or start planning on replacing them
FWIW..... I have a bin of children PFDs it's just part of having kids and an expensive hobby
Most of the ones I have are sterns brand and were purchased in the sporting goods store with the child in tow to ensure fit.
besides being a ford 302 with a 2-barrel carb, do you have a real question? or just a photodump and run?
the high output versions were not 2-barrels, they were fuel injected motors with F40 heads and a 351 cam and 215hp
you have a lowly 2-barrel motor with 190hp
you can get parts here...
unless the BBC needs a complete rebuild, I would just go boating.
when it does, look into the 6.3 aluminum heat exchanged LS / LT variants out there. 430+ hp and 400# less weight than the BBC, (200# less than the iron SBC)
or build a 550hp BBC
the aluminum is fastened with stainless hardware. the only thing that would be worse from a galvanic standpoint is if there was a copper washer bolted between.
