Edward
Thank you for your response.  I will check for dropped thrust bearings
though I am doubtful that is the cause.  The noise could certainly be that
grinding sound.  On this engine I machined the faces of one of the main
caps and pinned a second pair of thrust bearings in place (I had dropped
thrust bearings in the original GT6 engine).

You should check the end-play on the crankshaft as it could be that the
thrust bearing has failed. Push on the front pulley till the crank will
move no further backwards, have someone push the clutch pedal as you
observe the harmonic damper/pulley for movement forward.  The spec is
about .004.  If the bearing has fallen out it will about a 1/4" or more.
