Rick, thanks for correcting my Startup mistake, fingers & brain weren't syncronized.
Jtraik, yes, you can use Spacers/Washers if wanted/needed for additional clearance between the Engine & Trans bellhousing during breakin. It is difficult to monitor both simultaneously.
TC to Flexplate clearance should be 1/16" Min. to 3/16" Max. after tightening Bellhousing bolts.
