I was told it was a crate engine so not sure if it was built for marine use. My neighbor passed away so I have noway to ask further.
Is there a typical advanced timing for SBC 350 that I can shoot for to optimize total timing?
Yes, and here is an example.
NOTE... this is an example ONLY. See your OEM specs for your engine.
Otherwise, all i know to do is set the initial timing for maximum engine vacuum @ 550-600 RPM per the manual.
I think that your manual is referring to a low speed fuel/air mixture adjustment.
The low speed metering is adjusted as to achieve maximum manifold pressure.
Any change to BASE advance will also affect idle RPM.
Keep in mind that any change to BASE advance creates the same change to the Progressive and Total Advance.
I get it, its the only way to be 100% sure. PIA, but I see your point since I do not know for sure.
You will gain "Peace of Mind" if you do this!
