Stock timing in 1969 was set at 4 deg BTDC but that was before electronic ignition was standard on all Chevrolet's if you are running a electronic distributor set it at 8 deg BTDC and that should work fine for you.

The factory timing specs is low. I have seen gains of 20-40 HP by bumping the timing up and recurving the dist.
The SBC engines likes 36-38* total timing the best (with older bowl shaped head chambers)
Total timing is mech. advavce in the dist + the amount of timing at idle.
Most stock dist. gives right at 20* mech. advance.
So that means at idle you will need around 16-18*
16* idle timing + 20* mech. advance = 36* total timing

I do my 1961 Pontiac with a vacuum gauge...Yank the vacuum hose off of the distributor vacuum advance and put it on the gauge. Turn the distributor until you get the highest reading...shut it down....tighten everything up...Now fine tune it by adjusting the points in the same manner.
