After an expensive rebuild of my detonated 327 my builder/machine shop figured out the timing mark on my larger harmonic balancer from a 350 didn't jive with my 327. At TDC the mark was out 14 degrees so he scribed a new correct mark on my balancer.
This wasn't the first motor I lost to a bad timing mark. The first build didn't have forged pistons so it was toast after 40 miles. The 2nd build lasted 700 miles...fingers crossed for the 3rd build!
