That kind of timing tells you that your balancer/timing tab is really inaccurate or you’re reading your timing in the wrong spot on your 305.
A 305 should have a timing tube at the 12 o’clock position that you sight down to the balancer. Right behind the water pump.
Are you timing it with this or is there a timing tab at the 2 o’clock position?
Some info here.
