I just checked my manual. The point gap is .019 and the dwell is 28-32 degrees. Spark plug gap is .035. The original factory specs for the timing varies with the engine used. Stock 1969 Chevy El Camino with the 350 runs from 4 degrees BTDC to 8 degrees BTDC. This was slightly lower for California cars with the smog pumps.
My experience was that running 10-12 degrees BTDC gave the best overall performance for the stock 1969 350 cu in Chevy smallblock with a four barrel carb and a 4 speed trans.
