There is a bit of a case for tight front hub nuts in that it pre stresses the sharp radii. However the stubs do not fail there. (Other cars with taper rollers tre adjusted just finger tight) High torque just collapses the spacer piece.
Tab washers are dubious; the material has to be just right.
Split pins are a pain and the temptaion is to tighten to align. Very many Seven b.e bolts are stretched. Yet for non racers the bolts are very generously sized. If the caps seat properly it is debatable if any lock methd is required. (My Seven and Jowett ran without) Many other makes with 5/16 big ends much more stressed accept less than 20 ibs ft.
According to Machinerys Handbook the accuracy of torque wrench cf actual tension is +/- 25%, so if using high figures easy to snap.
