FWIW, Len Renkenberger, a machinist and long time TR6 guy based in Rhode
Island) says the .005 - .007 clearance on the TR6 thrust washer is overly
generous
and clearances as small as .002 will do quite nicely and will wear at a
slower pace.
Personal experience (ie: anecdotal): When I re-bearing'd my 6 pot engine I
got a set of STD and +.005 thrust washers and mixed one of each which resulted
in a clearance of just over .002 with no issures what-so-ever.
