This is not completely correct.
Stock, original, unmodified 68-70 cars have a distributor curved to aid
in the reduction of smog emissions, thus they are timed differently.
For PRE-68 cars (SU), timing is 16 BTDC
For 68 and newer that have the FACTORY distributor, the timing is
ZERO BTDC. If you run a stock 68-70 car with advance, you risk
detonation and eventual engine destruction.
If your 68 or newer car has either a pre-68 or a recurved distributor,
then the 16 degree figure is probably correct.
