Hey guys I've got this Chevy 305 and my timing marks are rusted over the harmonic balancer so i cannot read them, I've read the Seloc manual and it was not very informational. Does anyone know what the notches are as i cannot set my timing without them. Thanks

Re: 305 timing marks

The bottom of the big notch is TDC, the first point coming out of the big notch is 4*, each point past that is another 2*.
