What does the timing mark on a 1970 F350 with a 360 look like. The balancer/pulley was very rusty. I cleaned it up but still can not find a timing mark.

The mark on my '54 F-100 is a groove that runs perpendicular across. All I can see on the 70 is a groove that starts on one side and angles it way across to the other side from the side nearest the engine towards the side nearest the fan. It takes about half of the balancer to do this. I also see a few numbers or letters but they are not legible.

I want to set the timing but can not do it with out knowing what the mark looks like.

 

I thought I had a picture of my timing mark on the crank pulley from when i chdnged my timing chsin and gears but I don't. Have pics of everything else but the mark but I'm pretty sure it was a straight line across the outer ring. This was on my 71 f250 with a 360

 

Harmonic balancer same: 1968/76 F100/350 360/390 & 1968/71 Galaxie/LTD 390.

 

Thanks, Bill. Do your books have a pic of one showing the timing mark? I would figure that it is a groove across the balancer but I can not find one.

thanks, abe

 

Parts catalog doesn't show timing marks. I listed the applications for the balancer so that you and others would know what would be the same, what would not be.

 

It is a line across the harmonic balancer. If you can start the moter and from the bottom safely reach up with a peace of sand paper and lightly let it ride on the balancer and it will clean up the suface leaving the line dirty to see. I then fill that line with a yellow paint filled in .
