No, it does not need to be centered. As you rotate the crank the dial indicator will sweep 360* and you are looking for the runout measurement so it's all relative. Depending upon where you anchor the dial indicator you'll just be sweeping a circle with a given radius, move the indicator and the sweep radius changes. Before you check the runout, make sure to first check that the bellhousing (BH) is parallel to the block. I shimmed my BH to adjust the runout first and subsequently decided I should also check if the parallel measurement was within spec which it was not. Once I adjusted the parallel by shimming it I had to readjust the runout with the offset dowels.

What is the best way to check if the block and BH are parallel? Thanks
