355ci SBC with rumpy cam of some sort and roller rockers (standard ratio).
I timed it up the old school way...close enough to run and then moved the dizzy about for fastest idle.
I then put the timing light on it aiming for 8* BTDC at idle and around 34* at 3000 rpm but it was nowhere near my first setting.
Setting to the timing light needs the idle stop screw moving in a fairish way to get the idle up to speed.
Which is the best way to set the timing?...and don't say rolling road.
