I am lining up someone with a timing light... or I'll just go buy another one of my own. (mine is a war prize for the ex) I have looked through numerous threads on here, and anywhere else I can find information, and can't seem to come up with what I need to know.

According to the service manual, the timing is supposed to be set to 5 degrees. According to the timing (pulley?/disk?) on the crank, that would be the dot in between the two lines in the picture. If the letters are not visible in the picture, it says from the top down U - D - C - 1 - 10.

I have read many threads about the 305's and no one really seems to say where their timing is set at. I don't currently know where mine is at, until I get the light.

Any suggestions on where to set it, and is there any special procedures to follow with this engine?

I have the Holley 500 carb, and Pertronix ignition, if that affects anything.
