I have 1967 440 HP motor. It recently has been fully rebuilt. All new internals. I installed the original Harmonic Balancer with no problems. I went to find TDC by using the thumb over the hole whilen cranking technique. When my thumb blew off I looked at the mark on the Balancer and it was way off! Like just over 45 degrees BTDC! I thought he original balancer had skipped or spun out of wack due its age. I replaced it with a Super Damper. SAME THING! It shows 45 degress Adavanced WHAT NOW ? I don't see how the new double roller timing chain skipped a tooth? Amy help would be greatly appreciated!
