SBC 350 Timing Question

I recently installed a new SBC 350 and am needing to set the time today. I have an adjustable timing light but can't remember what a SBC should be set at. The 1970 440 Charger I last worked on ran great set at 32*. Anyone suggest a good starting place for the timeing?

are you running a vacuum advance distributor? i run my sbc's with mechanical advance only and i have advance all in around 2800 with light to medium advance springs, which is also the stall speed on my converter (i always try to match converter stall speed, when mechanical advance comes in, and cam power-range - this makes for nice performance); and i run total advance 32-34 degrees, and i run the most base advance i can run and have the engine start easy..depending on how old the engine is and what condition its in, set it for 30 degrees total advance and listen for pinging and check the plugs, then go up to 32, or 34, whatever it will run without pinging, knocking, or over-heating the plugs..run r-43's or r-42's and a 180 t-stat and you should be able to get 34 degrees total out of it safely.

i am also not concerned or accounting for emissions or fuel economy with my applications.

need to know the year of the motor...
carb, tbi or tpi.
tbi, all you can do is set the base timing, the ecm will do everything else for ye, so not a lot to do there....tpi is the same IIRC.

Set the base at 8-10 degrees and make sure the total advance doesnt go over 35 or so.
