recomended timing advanced for 4mm crank?

[twinrock]

hey guys i just got a adjustable timing plate..now i see that alot of pple adjust about 4deg on a stock engine..i have a 4mm stroke crank..would the 4deg still be aplicable or go more as i heard that a 4mm crank retards the timing a bit to start off with thanks..?

I ran 6 on mine on race fuel and ran great. Watch for plugs backing out and pinging noises, if so may have to back it down again. Going to depend some on the domes you are running as well. Custom cut? And if so, by who?
