I am running a comletely stock 1972 350 chevy with a q-jet carb and Hei dist.I am curious as to about how much total advance I can run with out causing proublems.The dist I have is giving me about 34 degrees total advance at 3000 rpms.Is this more advance than most Hei distributers ? I am afraid if I set my base timing at 6 or 10 degrees I will burn valves or worse,since that will give me about40 to 44 degrees at full advance.I am also required to run pump gas in my class.

i read an article though that said a sb needs about 25 to 30 degrees at idle to be responsive , maybe not with a stock production engine though.
