When crank is installed with bearings and caps all torqued to specs with plastic gauge guaging the clearences. Is these the true clearence figures even though there is no oil wedge holding crank off upper bearings and caps? It seems as though one will get both side measurements in this case?

That is the measurement that you want. Say the plastiguage says .002. That means the bearing circle is .002 bigger than the journal. However, I would not rely on plastiguage. Take the block to the machine shop or do this yourself. Mic the inside of the rods or the mains torqued without bearings to make sure they are within the tolerance for proper crush of the bearings. Then Mic the inside with the bearing installed and torqued. Measure them one way and then turn 90 degrees and measure. Then Mic the journal once and turn 90 and measure again. The inside diameter minus the journal diameter is your clearance.
That is my opinion though, and you know they are like.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
