What is the timing for a 1986 Chevy 305?

here the best answer i can give you on the timing of a 305 Chevy engine i seen timing on these engines from 0 to 13 btdc the best way to set the timing is to disconnect the est plug and start the enginge and very slowly turn the dis. and listen to the engine until it runs the smoothest then turn it off and reconnect the est plug and try restarting it it should start nicely if not then you need to readjust the dis. my 305 which is a 1985 is happy at 12deg. btdc. but is built up a little and no poluion bull on it

Mine runs good at 8-10 BTDC
