318 timing mark

I used a '74 318 cover & 273 h2o pump...saw that timing marks were an issue. I made a piston stop out of spark plug w/all thread, and rotated back to stop and forward to stop, a few times to establish consistency (carefully!!) Divided by two and established zero that way. I then took my old timing pointer off of my 273, attached it and at Zero on timing tab I scribed a line in my balancer for my new TDC.


(Then painted over old timing mark
