i measured the Stroke from TDC to BDC with dial gauge on each test, and digital verniers in a jig bolt to the top of the block.

And each test was carried out twice on each bore with identical results to 0.01mm.


Whats plasti-gauge?

all i done was build the bottomend with gearoil.





Also checked TDC and BDC on different bores, and they are true to each bore, meaning TDC @ 1 is TDC @ 4, and BDC @ 2 and 3.
